CS8128
CS8128
5V Linear Controller/Driver
Description
The CS8128 contains all the necessary control circuitry to implement a 5V linear
regulator.
An external pass device is used to produce superior performance compared to conventional monolithic
regulators.
The CS8128 with a TIP42
PNP transistor typically provides a 100mV dropout voltage at 500mA, increasing to 350mV at 3A.
Quiescent current at 500mA is only 5mA.
Monolithic
regulators cannot approach these figures because their power
transistors do not provide the high beta and excellent saturation characteristics at high currents.
The CS8128 is compatible with a wide variety of external
transistors, allowing flexibility for thermal, space,...
