SM72238

SolarMagic Micropower Voltage Regulator

General Description

Features

The SM72238 is a micropower voltage regulator with very low

quiescent current (75μA typ.) and very low dropout voltage

(typ. 40mV at light loads and 380mV at 100mA). It is ideally

suited for use in battery-powered systems. Furthermore, the

quiescent current of the SM72238 increases only slightly in

dropout, prolonging battery life.

Renewable Energy Grade

■

High accuracy output voltage

Guaranteed 100mA output current

Extremely low quiescent current

Low dropout voltage

Extremely tight load and line regulation

The SM72238 is available in the surface-mount D-Pak pack-

age.

Very low temperature coefficient

Careful design of the SM72238 has minimized all contribu-

tions to the error budget. This includes a tight initial tolerance

(.5% typ.), extremely good load and line regulation (.05% typ.)

and a very low output voltage temperature coefficient, making

the part useful as a low-power voltage reference.

Use as Regulator or Reference

Needs minimum capacitance for stability

■

Current and Thermal Limiting

Stable with low-ESR output capacitors (10mΩ to 6Ω)
