) Dropout Voltage at 300mA ■ Extremely Tight Load and Line Regulation ■ Current & Thermal Limiting ■ Reverse Battery Protection ■ Equivalent Replacement For LT1521 SPX1521 3 Pin TO-263 1 2 3 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 computers.
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.
