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.

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.
