MIC2940A/2941A
1.2A Low-Dropout Voltage Regulator
General Description
The MIC2940A and MIC2941A are “bulletproof” efficient
voltage regulators with very low dropout voltage (typically
40mV at light loads and 350mV at 1A), and low quiescent
current (240µA typical). The quiescent current of the
MIC2940A increases only slightly in dropout, thus
prolonging battery life. Key MIC2940A features include
protection against reversed battery, fold-back current
limiting, and automotive “load dump” protection (60V
positive transient).
The MIC2940 is available in both
fixed
voltage (3.3V, 5V,
and 12V) and adjustable voltage configurations. The
MIC2940A-xx devices are three pin,
fixed
voltage
regulators. A logic-compatible shutdown input is provided
on the adjustable MIC2941A, which enables the regulator
to be switched on and off.
Data sheets and support documentation can be found on
Micrel’s web site at: www.micrel.com.
