FSP2133
„ GENERAL DESCRIPTION
The FSP2133 is a positive adjustable voltage linear
regulator features low quiescent current (Typ. 65µA)
and low dropout voltage, making it 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
SOT23-5L 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.
