AP1157ADVXX
14V Input / 100mA Output LDO Regulator
1. Genaral Description
The AP1157ADVXX is a low dropout linear regulator with ON/OFF control, which can supply 100mA load
current. The IC is an integrated circuit with a silicon monolithic bipolar structure. The output voltage, trimmed
with high accuracy, is available from 1.3 to 5.5V in 0.1V steps. The output capacitor is available to use a small
0.22μF ceramic capacitor. The over current, thermal and reverse bias protections are integrated, and also the
package is small and thin type, HSON0202-6. The IC is designed for space saving requirements.
