GENERAL DESCRIPTION

The FSP2131 series of positive voltage linear

regulators feature low quiescent current (Typ. 65µA)

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

SOT23-3L package is attractive for portable and

handheld applications. They have both thermal

shutdown and a current limit feature to prevent device

failure from extreme operating conditions. They are

stable with an output capacitor of 2.2µF or greater.
