DESCRIPTION
The SPX1521 is a low power voltage regulator. This device is an excellent choice for use in batterypowered 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.
