Description

The AP2117 is positive voltage regulator IC designed by

CMOS process. The AP2117 has features of low dropout

voltage, low noise, high output voltage accuracy and low

current consumption. It consists of a voltage reference, an

error amplifier, a resistor network for setting output volt-

age, a current limit circuit for current protection, a circuit

for over-temperature protection, and a chip enable circuit.

Thus, the AP2117 is suitable for various power sources

for portable application.
