Selectable Adjustable/Fixed Low Dropout 300mA Linear RegulatorThe 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. By Anpec Electronics Corporation
