1. Genaral Description
The AP1155ADU is a low dropout linear regulator with ON/OFF control, which can supply 1A load current. The
IC is an integrated circuit with a silicon monolithic bipolar structure. The output voltage can be set from 1.3V to
14.0V by external resistors. 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 high heat radiation type,
TO252-5. The IC is designed for high power application.
