SM72238 SolarMagic Micropower Voltage Regulator
General Description
The SM72238 is a micropower voltage regulator with very low quiescent current (75A 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.
