SM72238 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 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...
