Description

General part information

MIC2571 Series

MIC2571 is a micropower boost switching regulator that operates from one alkaline, nickel-metal-hydride cell, or lithium cell.

The MIC2571 accepts a positive input voltage between 0.9V and 15V. Its typical no-load supply current is 120µA.

The MIC2571 is available in selectable fixed output or adjustable output versions. The MIC2571-1 can be configured for 2.85V, 3.3V, or 5V by connecting one of three separate feedback pins to the output. The MIC2571-2 can be configured for an output voltage ranging between its input voltage and 36V, using an external resistor network.
