300MA ADJUSTABLE HIGH PSRR CMOS LINEAR REGULATOR FSP2133 „ z z z z z z z z z z z z FEATURES Low dropout voltage: 180mV at 300mA (Vo=3.3V) Quiescent current: Typ. 65µA ±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: 0.5µA Space saving SOT23-5L package „ 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. „ z z z z z z z APPLICATIONS Cordless phones Cellular phones Bluetooth earphones Digital Cameras Portable electronics WLANs MP3 players „ PIN CONFIGURATION (Top View) 1 2 3 5 4 „ PIN DESCRIPTION Pin Number 1 2 3 4 5 Pin Name VIN GND EN ADJ VOUT Pin Function Input Ground Chip Enable (active high) Adjustable pin Output www.DataSheet4U.com „ BLOCK DIAGRAM 1/8 2007-4-19 300MA ADJUSTABLE HIGH PSRR CMOS LINEAR REGULATOR FSP2133 „ TYPICAL APPLICATIONS CIRCUITS „ ABSOLUTE MAXIMUM RATINGS Parameter ...
