z Quiescent current: Typ. 65µA
z 2% Voltage Accuracy
z High PSRR: 70dB at 1KHz
z Thermal Shutdown
z Current Limiting
z Excellent line and load regulation
z Fast response
z Short circuit protection
z Low temperature coefficient
z Space saving SOT23-3L package
FSP2131
„ 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.
„ APPLICATIONS
z Cordless phones
z Cellular phones
z Bluetooth earphones
z Digital Cameras
z Portable electronics
z WLANs
z MP3 players
