MIC2937A/29371/29372
General Description
The MIC2937A family are “bulletproof” ef?cient voltage regu-
lators with very low dropout voltage (typically 40mV at light
loads and 300mV at 500mA), and very low quiescent current
(160μA typical). The quiescent current of the MIC2937A in-
creases only slightly in dropout, thus prolonging battery life.
Key MIC2937A features include protection against reversed
battery, fold-back current limiting, and automotive “load dump”
protection (60V positive transient).
The MIC2937 is available in several con?gurations. The
MIC2937A-xx devices are three pin ?xed voltage regulators
with 3.3V, 5V, and 12V outputs available. The MIC29371 is
a ?xed regulator offering logic compatible ON/OFF switching
input and an error ?ag output. This ?ag may also be used as
a power-on reset signal. A logic-compatible shutdown input
is provided on the adjustable MIC29372, which enables the
regulator to be switched on and off.
