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.
