300mA FIXED OUTPUT VOLTAGE LDO REGULATOR
Product Brief
AP2117
Description
Parametric Table
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.
