GENERAL DESCRIPTION
The LSP2133 is a positive adjustable voltage linear
regulator features low quiescent current (Typ. 65A)
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 2.2F or greater.
FEATURES
Low dropout voltage: 180mV at 300mA (Vo=3.3V)
Quiescent current: Typ. 65A
±2% Voltage Accuracy
High PSRR: 67dB at 100Hz
Thermal Shutdown
Current Limiting
Excellent line and load regulation
Fast response
Short circuit protection
Low temperature coefficient
Shutdown current: 0.5A
Space saving SOT23-5L package
