Basic types of IC regulators
Most ic voltage regulator have one of these types of output voltage : fixed positive, fixed negative, or adjustable. IC regulators with fixed positive or negative output are factory-trimmed to get to get different fixed voltage with magnitudes form about 5 to 24 V. IC regulators with an adjustable output can vary the regulated output voltage from less than 2 to more than 40 V.
IC regulators are also classified as standard, low power, and low dropout. Standard IC regulators are designed for straightforward and noncritical applications. With heat sinks, a standard IC regulator can have a load current of more than 1 A.
If load currents up to 100 mA are adequate, low-power IC regulators are available in TO-92 packages, the name size used for small-signal transistors like the 2N3094. Since these regulators do not require heat sinking, they are convenient and easy to use.
The drop voltage of an IC regulators is the defined as the minimum headroom voltage needed for regulation. For instance, standard IC regulators have a dropout voltage of 2 to 3 V. This means that the input voltage has be at least 2 to 3 V greater than the regulated output voltage for the chip to regulate to specifications. In applications in which 2 to 3 V of headroom is not available, low dropout IC regulators can be used. These regulators have typical dropout voltages of 0.15V for a load current of 100 mA and 0.7 V for a load current of 1 A.
THE LM7800 SERIES
The LM78XX series (where XX= 05, 06, 08, 10, 12, 15, 18, or 24) is typical of the three-terminal voltage regulators. The 7805 produce are output of +5 V, the 7806 produce +6 V, the 7808 produce +8 V, and so on, up to the 7824, which produce a output of +24 V.
Figure 2. shows the function block diagram of the 78XX series. A built-in reference voltage Vref drivers the noniverting input of an amplifier. The voltage regulation is the similar to our earlier discussion. A voltage driver consisting of R_1^' and R_2^' samples the output voltage and returns a feedback voltage to the inverting input of the high-gain amplifier. The output voltage is given by :
V_out = (R_1^'+ R_2^')/(R_1^' ) V_ref
In this equation, the reference voltage is equivalent to the zener voltage in our earlier discussions. The primes attached to R_1^' and R_2^' indicate that these resistors are inside the IC itself, rather than being external resistors. These resistors are factory-trimmed to get different output voltages (5 to 24 V) in the 78XX series. The tolerance of the output voltage is ± 4 percent.
The LM78XX includes a pass transistor that can be handle 1 A of load current, provided that adequate heat sinking is used. Also included are thermal shutdown and current limiting. Thermal shutdown means that the chip will shut itself of when the internal temperature becomes too high, around 175oC. This is a precaution against excessive power dissipation, which depends on the ambient temperature, type of heat sinking, and other variables. Because of thermal shutdown and current limiting, devices in the 78XX series are almost indestructible.

Jenis dasar IC regulator
Kebanyakan regulator tegangan ic memiliki salah satu jenis tegangan output: tetap positif, tetap negatif, atau disesuaikan. IC regulator dengan output positif atau negatif tetap adalah pabrik-dipangkas untuk mendapatkan untuk mendapatkan tegangan tetap berbeda dengan besaran membentuk sekitar 5 sampai 24 V. IC regulator dengan output disesuaikan dapat bervariasi tegangan output diatur dari kurang dari 2 sampai lebih dari 40 V.
IC regulator juga tergolong standar, daya rendah, dan putus sekolah rendah. Standar IC regulator dirancang untuk aplikasi mudah dan tidak terlalu penting. Dengan heat sink, IC regulator standar dapat memiliki arus beban lebih dari 1 A.
Jika arus beban hingga 100 mA memadai, daya rendah IC regulator yang tersedia di TO-92 paket, ukuran nama yang digunakan untuk sinyal kecil transistor seperti 2N3094. Sejak regulator ini tidak memerlukan panas tenggelam, mereka nyaman dan mudah digunakan.
Penurunan tegangan IC regulator adalah didefinisikan sebagai tegangan ruang kepala minimum yang diperlukan untuk regulasi. Misalnya, standar IC regulator memiliki tegangan putus sekolah dari 2 sampai 3 V. Ini berarti bahwa tegangan input memiliki minimal 2 sampai 3 V lebih besar dari tegangan output diatur untuk chip untuk mengatur spesifikasi. Dalam aplikasi di mana 2 sampai 3 V dari ruang kepala tidak tersedia, putus sekolah rendah IC regulator dapat digunakan. Regulator ini memiliki tegangan putus sekolah khas 0.15V untuk arus beban dari 100 mA dan 0,7 V untuk arus beban dari 1 A.
THE SERIES LM7800
The LM78xx seri (di mana XX = 05, 06, 08, 10, 12, 15, 18 , atau 24) khas dari regulator tegangan tiga terminal. 7.805 hasil adalah output dari +5 V, 7806 menghasilkan +6 V, 7808 menghasilkan +8 V, dan seterusnya, hingga 7824, yang menghasilkan output dari 24 V.
Gambar 2. menunjukkan diagram blok fungsi dari seri 78XX. Built-in tegangan referensi driver Vref masukan noniverting dari sebuah penguat. The pengaturan tegangan adalah sama dengan pembahasan sebelumnya kita. Seorang pengemudi tegangan yang terdiri dari R_1 ^ 'dan R_2 ^' sampel tegangan output dan mengembalikan tegangan umpan balik ke input pembalik dari gain tinggi amplifier. Tegangan output diberikan oleh:
V_out = (R_1 ^ '+ R_2 ^') / (R_1 ^ ') V_ref
Dalam persamaan ini, tegangan referensi adalah setara dengan tegangan zener dalam diskusi sebelumnya kita. Bilangan prima melekat R_1 ^ 'dan R_2 ^' menunjukkan bahwa resistor ini berada di dalam IC itu sendiri, bukannya resistor eksternal. Resistor ini adalah pabrik-dipangkas untuk mendapatkan tegangan output yang berbeda (5 sampai 24 V) di seri 78XX. Toleransi tegangan output ± 4 persen.
The LM78xx termasuk transistor lulus yang dapat menangani 1 dari arus beban, asalkan tenggelam panas yang cukup digunakan. Juga termasuk yang thermal shutdown dan membatasi arus. Thermal shutdown berarti bahwa chip akan menutup sendiri ketika suhu internal menjadi terlalu tinggi, sekitar 175oC. Ini adalah pencegahan terhadap disipasi daya yang berlebihan, yang tergantung pada suhu lingkungan, jenis tenggelam panas, dan variabel lainnya. Karena thermal shutdown dan membatasi arus, perangkat dalam seri 78XX yang hampir tidak bisa dihancurkan.
