Block Diagram
Detailed Description
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.
safety when the junction temperature is larger than 140℃ or output current is larger than 1.2A.
by careful design considerations. The temperature coefficient is under 100ppm/℃. And the accuracy of
output voltage is guaranteed by trimming technique.
Typical Application
ACE1117C has an adjustable version and five fixed versions, Chart 1 is typical application:
