AP1154ADLXX
14V Input / 1A Output LDO Regulator
1. Genaral Description
The AP1154ADLXX 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, trimmed with high
accuracy, is available from 1.8 to 5.0V in 0.1V steps. The output capacitor is available to use a small 1μF ceramic
capacitor. The IC can be used for USB application (500mA), since the output limitation current can be set by
external resistor. The over current, thermal and reverse bias protections are integrated, and also the package is
high heat radiation type, HSOP-8. The IC is designed for space saving requirements.
