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.
