1 / 9 page 1 Date: 12/20/05 SPX1121 150mA Low DropoutVoltage Regulator © Copyright 2005 Sipex Corporation 150mA Low Dropout Voltage Regulator SPX1121 DESCRIPTION FEATURES ■ 5.0V and 3.3V output versions ■ 1% Output Accuracy ■ Very Low Quiescent Current ■ Low Dropout: 300mV @ 150mA ■ Very Tight Load & Line Regulation ■ Very Low Temperature Coefficient ■ Current and Thermal Limiting ■ Requires only 1µF for Stability ■ Equivalent Replacement for LT1121 ■ Industry Standard SOT-223 and TO-92 3 lead packages ® The SPX1121 is a low power voltage regulator. It is an excellent choice for use in battery-powered applications such as cordless telephones, radio control systems, and portable computers. The SPX1121 features very low quiescent current and low dropout voltage (typ. 20mV at 100µA and 300mV at 150mA). A tight initial tolerance (1%), extremely good load and line regulation (0.05% typ.), and very low output temperature coefficient (20 ppm/°C typ.), make the SPX1121 useful as a low power voltage reference. 13 2 V OUT GND SOT-223 Package (M3) Front View V IN SPX1121 GND + 2.2µF + SPX1121 I IN I G I L 5V IN OUT GND LOAD I IN= I L+ I G V IN 0.1µF Figure 1.
