SM72238
May 9, 2011
SolarMagic Micropower Voltage Regulator
General 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 pack-
age.
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.
