ACE1117H
1A Bipolar Linear Regulator
Detailed Description
ACE1117H is a series of low dropout voltage, three terminal regulators. Its application circuit is very
simple: the fixed version only needs two capacitors and the adjustable version only needs two resistors
and two capacitors to work. It is composed of some modules including start-up circuit, bias circuit,
bandgap, thermal shutdown, current limit, power transistors and its driver circuit and so on.
The thermal shut down modules can assure chip and its application system working safety when the
junction temperature is larger than 140℃.
The bandgap module provides stable reference voltage, whose temperature coefficient is compensated
by careful design considerations. The temperature coefficient is under 100ppm/℃. And the accuracy of
output voltage is guaranteed by trimming technique.
