DESCRIPTION

The SPX52 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 SPX52 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 SPX52 is offered in 3 pin TO-252, SOT-223, TO-220 & TO-263 packages.
