SNVS694C –JANUARY 2011–REVISED APRIL 2013

Micropower Voltage Regulator

Check for Samples: SM72238

FEATURES

DESCRIPTION

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

Ensured 100mA Output Current

Extremely Low Quiescent Current

Low Dropout Voltage

Extremely Tight Load and Line Regulation

Very Low Temperature Coefficient

Use as Regulator or Reference

Needs Minimum Capacitance for Stability

Current and Thermal Limiting

The SM72238 is available in the surface-mount D-

Pak package.

Careful design of the SM72238 has minimized all

contributions 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.

Stable With Low-ESR Output Capacitors

(10mΩ to 6Ω)
