The quiescent current of the MIC2920A increases only slightly in dropout, prolonging battery life.
Key MIC2920A features include protection against reversed battery, fold-back current limiting, and automotive “load dump” protection (60V positive transient).
The MIC2920 family of devices are available in several configurations.
The MIC2920A-x.
x devices are 3-lead fixed-voltage regulators available in 3.
3V, 4.
85V, 5V, and 12V outputs.
The MIC29201 is a fixed-voltage regulator that offers a logic-compatible ON/OFF (shutdown) input and an error flag output.
This flag may also be used as a power-on reset signal.
A logic-compatible shutdown input is provided on the adjustable MIC29202, which allows the regulator to be switched on and off.
The MIC29204 8-lead SOIC adjustable regulator includes both shutdown and error flag pins and may be pin-strapped for 5V output or programmed from 1.
