PRODUCT DESCRIPTION

The SPX8863 is a low-power positive voltage regulator with ultra low noise output and very low dropout voltage. In addition, this

device offers very low quiescent current of approximately 600uA at 100mA output. The SPX8863 initial tolerance is less than 1%

max and has a logic compatible ON/OFF switching input. The unique features of the SPX8863 include a reference bypass pin for the

best performance results of low noise.

This device is an excellent choice for use in battery powered applications such as cellular/ cordless telephones, radio control systems,

and portable computers. When disabled power consumption drops to nearly zero. The device also has a very low output temperature

coefficient, making it a low power voltage reference. The SPX8863 key features include protection against reversed battery, fold-back

current limiting, and automotive load dump protection.

The SPX8863 is available in many fixed voltages (1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 4.0V, 4.5V, & 5.0V) or with an adjustable output.

This device is offered in a small 5-pin SOT-23 package, providing a small footprint with all the performance features with fixed or

adjustable output.
