300mA HIGH PSRR LOW-DROPOUT CMOS LINEAR REGULATOR
Description
The PAM3101 series of positive voltage linear regulators feature low
quiescent current (65µA typ.) and low dropout voltage, making them
ideal for battery powered applications. Their high PSRR make them
useful in applications where AC noise on the input power supply must
be suppressed. Space-saving TSOT25, SOT-23, SOT-89, SC70 and
DFN1.6x1.6-6L packages are attractive for portable and handheld
applications. They have both thermal shutdown and current limit
features to prevernt device failure from extreme operating conditions.
They are stable with an output capacitor of 2.2µF or greater.
