1 / 5 page 1 Date: 5/25/04 SPX1129 400mA Low Dropout Voltage Regulator ©Copyright 2004 Sipex Corporation SPX1129 DESCRIPTION FEATURES ■ 1% Output Accuracy 3.3V, 5V, at 500mA Output ■ Very Low Quiescent Current ■ 0.42V Dropout Voltage at 400mA ■ Extremely Tight Load and Line Regulation ■ Current & Thermal Limiting ■ Reverse Battery Protection ■ Equivalent Replacement For LT1129 APPPLICATIONS ■ Power Supply ■ Communications Equipment ■ Computers and Peripherals ® The SPX1129 is a low power voltage regulator. This device is an excellent choice for use in battery-powered applications such as cordless telephones, radio control systems, and portable computers. The SPX1129 features very low quiescent current and very low dropout voltage of 0.42 volts. This includes a tight initial tolerance of ±1% max, and a very low output temperature coefficient, making the SPX1129 useful as a low- power voltage reference. The SPX1129 is offered in a SOT-223, TO-220, TO-252 & TO-263 3 lead packages. 400mA Low Dropout Voltage Regulator + 2.2µF + SPX1129 I IN I G I L 5V IN OUT GND LOAD I IN = IL + IG V IN 0.1µF Fixed +5V Regulator Circuit..
