National Semiconductor SM72238
The SM72238 is a micropower voltage regulator with very low quiescent current (75μA typ.) and very low dropout voltage (typ. It is ideally suited for use in battery-powered systems. The SM72238 is available in the surface-mount D-Pak package.GENERAL DESCRIPTION
40mV at light loads and 380mV at 100mA). Furthermore, the quiescent current of the SM72238 increases only slightly in dropout, prolonging battery life. 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.FEATURES
