MIC2940A/2941A

1.2A Low-Dropout Voltage Regulator

General Description

Features

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).

• High output voltage accuracy

• Guaranteed 1.25A output

• Low quiescent current

• Low dropout voltage

• Extremely tight load and line regulation

• Very low temperature coefﬁcient

• Current and thermal limiting

• Input can withstand –20V reverse battery and +60V

positive transients

• Logic-controlled electronic shutdown

• Output programmable from 1.24V to 26V(MIC2941A)

• Available in TO-220, TO-263, TO-220-5, and TO-263-5

packages.

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.

Micrel’s web site at: www.micrel.com.
