PAM3131
3A ADJUSTABLE LOW VOLTAGE LOW DROPOUT CMOS REGULATOR
Description
The PAM3131 is a 3A CMOS adjustable LDO regulator that features
a low quiescent current, ultra low input, output, and dropout voltages,
as well as over temperature protection. It is available in TO-263 and
PSOP-8 (Exposed Pad) packages. The output voltage is adjustable
from 0.9V to 3.3V. The PAM3131 is stable with a ceramic output
capacitor of 1.0μF or higher.
This family of regulators can provide either a stand alone power
supply solution or act as a post regulator for switch mode power
supplies. They are particularly well suited for applications requiring
low input and output voltages.

Notes:
1. The minimum input voltage ( ) of the PAM3131 is determined by output voltage and dropout voltage. The minimum input voltage is defined as:
2. Output current is limited by PD, maximum IO = PD/(VIN(MAX) -VO).
