Advance Information

Description

The Bay Linear L48XX this series of fixed-voltage monolithic

micro-power voltage regulators is designed for a wide range of

applications. This device excellent choice in battery- powered

application. Furthermore, the quiescent current increases only

slight at dropout, which prolong battery life.

This series of fixed voltage regulators features very low

quiescent current (100mATyp.) and very low drop output

voltage (Typ. 60mV at light load and 420mV at 400mA). This

includes a tight initial tolerance of 0.5%Typ., extremely good

load and line regulation of 0.05%typ., and very low output

temperature coefficient.

This series of fixed-voltage regulator is offered in 3-pin TO-

220 package compatible with other fixed-voltage regulators.

Adjust model is offered in 5-pin TO-220 package and fixed

model with shutdown input is offered in 4-pin TO-220

package.
