Selectable Adjustable/Fixed Low Dropout 300mA Linear Regulator

The APL5317 is a low dropout linear Regulator which only needs a single input voltage supply from 2.8~6V, and it CAN deliver current up to 300mA to a set output voltage. It CAN work with low ESR ceramic capacitors, that make it ideal for using in the battery-powered applications, such as notebook computers and cellular phones. Its typical dropout voltage is only 230mV at 300mA loading. The APL5317 provides two output volt- age operation modes, the fixed output voltage mode and the adjustable output voltage, controlled by the SET pin for setting the output voltage. The fixed output voltage mode sets the output to a preset voltage (only 1.2V avail- able now) in the chip by connecting SET pin to ground, and the adjustable output voltage mode needs two resistors as a voltage divider connected to SET pin to define the output. The current-limit with current foldback and thermal shutdown functions protect the device against current over-loads and over temperature. The APL5317 is available in a SOT-23-5 package.
