APE8903A

3A LOW DROPOUT REGULATOR WITH ENABLE

FEATURES

DESCRIPTION

APE8903A is a high performance positive voltage

Adjustable Output Low to 0.8V

regulator designed for use in applications requiring very low

Input Voltage as Low as 1.4V and VPP Voltage 5V

600mV Dropout @ 3A, VO 1.2V

Over Current and Over Temperature Protection

Enable Pin (Internal Pull Low)

Low Reverse Leakage (Output to Input )

±2% Output Voltage

Input voltage and very low dropout voltage at up to 3 amps.

It operates with a VIN as low as 1.4V and VPP voltage 5V

with output voltage programmable as low as 0.8V.

APE8903A features ultra low dropout, ideal for applications

where VOUT is very close to VIN. Additionally, the

APE8903A has an enable pin to further reduce power

dissipation while shutdown. APE8903A provides excellent

regulation over variations in line, load and temperature.

APE8903A provides a power OK signal to indicate if the

voltage level of VO reaches 92% of its rating value.

APE8903A is available in the exposed SOP-8(MP)

package. It is available with 1.2V, 1.5V, 1.8V and 2.5V

internally preset outputs that are also adjustable using

external resistors.
