GENERAL DESCRIPTION
The FSP2130 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.
APPLICATIONS
Cordless phones
Cellular phones
Bluetooth earphones
Digital Cameras
Portable electronics
WLANs
MP3 players
