SPX1521 Datasheet | Sipex

FEATURES - 1% Output Accuracy 3.3V, 5V, at 300m A Output - Very Low Quiescent Current - 0.3V (Typ.) Dropout Voltage at 300m A - Extremely Tight Load and Line Regulation - Current & Thermal Limiting - Reverse Battery Protection - Equivalent Replacement For LT1521 3 Pin TO-263 VOUT GND VIN Now Available in Lead Free Packaging DESCRIPTION The SPX1521 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 puters. The SPX1521 features very low quiescent current and very low dropout voltage. This includes a tight initial tolerance of ±1% max, and very low output temperature coefficient, making the SPX1521 useful as a low-power voltage reference. The SPX1521 is offered in 3 pin TO-252, SOT-223, TO-220 & TO-263 packages.
