300mA ADJUSTABLE HIGH PSRR CMOS LINEAR REGULATOR
Description
The PAM3103 is a positive, adjustable linear regulator. It features low
quiescent current (65µA typ.) and low dropout voltage, making it ideal
for battery powered applications. The output voltage is adjustable
from 1.2V through 5V. Its high PSRR makes it useful in applications
that require AC noise suppression on the input power supply. Space-
saving TSOT25 and SOT353(SC70-5) packages are attractive for
portable and handheld applications. It has both thermal shutdown and
a current limit features to prevent device failure under extreme
operating conditions. It is stable with an output capacitor of 2.2µF or
greater.
