MIC2920X

400 mA Low Dropout Regulators

Features

General Description

• High Output Voltage Accuracy

• Ensured 400 mA Output

The MIC2920 family (MIC2920A, MIC29201,

MIC29202, and MIC29204) are efficient voltage

regulators with very low dropout voltage (typically

40 mV at light loads and 370 mV at 250 mA) and very

low quiescent current (140 μA typical). 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).

• Low Quiescent Current

• Low Dropout Voltage

• Extremely Tight Load and Line Regulation

• Very Low Temperature Coefficient

• Current and Thermal Limiting

• Input Withstands –20V Reverse Battery and +60V

Positive Transients

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

• Error Flag Warns of Output Dropout

• Logic-Controlled Electronic Shutdown

• Output Programmable from 1.24V to 26V

(MIC29202/MIC29204)

• Available in TO-220-3, TO-220-5, and

Surface-Mount TO-263-5, SOT-223, and SOIC-8

Packages

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 1.24V to 26V using two external

resistors.

Applications
