MIC2954

250mA Low-Dropout Regulator

General Description

Features

The MIC2954 is a “bulletproof” efficient voltage regulator

with very low dropout voltage (typically 40mV @ light loads

and 375mV @ 250mA), and low quiescent current (120µA

typical). The quiescent current of the MIC2954 increases

only slightly in dropout, thus prolonging battery life. Key

MIC2954 features include protection against reversed

battery, fold-back current limiting, and automotive load

dump protection (60V positive transient).

• High-accuracy 5V, guaranteed 250mA 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

The MIC2954-07/08BM is an adjustable version that

includes an error flag output that warns of a low output

voltage, which is often due to failing batteries on the input.

This may also be used as a power-on reset. A logic-

compatible shutdown input is provided which enables the

regulator to be switched on and off. This part may be pin-

strapped for 5V output, or programmed from 1.24V to 29V

with the use of two external resistors.

• Error flag warns of low output voltage

• Logic-controlled electronic shutdown

• Output programmable from 1.24V to 29V

(MIC2954-07/08)

• Available in TO-220, TO-92, and surface-mount SOT-

223 and SOIC-8 packages

Applications

The MIC2954 is available in two voltage tolerances, ±0.5%

maximum and ±1% maximum. Both are guaranteed for

junction temperatures from –40°C to +125°C.

• Battery powered equipment

• Cellular telephones

• Laptop, notebook, and palmtop computers

• PCMCIA V_CCand V_PPregulation/switching

• Bar code scanners

• Automotive electronics

• SMPS post-regulator/dc-to-dc modules
