MIC5321

Dual, High Performance

150mA µCap ULDO™

General Description

Features

The MIC5321 is a tiny Dual Ultra Low-Dropout

(ULDO™) linear regulator ideally suited for those

applications that require high PSRR because it

provides a bypass pin for those noise sensitive

portable electronics. The MIC5321 integrates two

high-performance; 150mA ULDOs into a very compact

1.6mm x 1.6mm leadless Thin MLF^®package that

provides exceptional thermal package characteristics.

•

2.3V to 5.5V input voltage range

Ultra-low dropout voltage ULDO™ 35mV @

150mA

Tiny 6-pin 1.6mm x 1.6mm Thin MLF^®leadless

package

•

Low cost TSOT-23-6 package

Bypass pin for improved noise performance

High PSRR – >75dB on each LDO

Ultra low noise output - > 30µVrms

Dual 150mA outputs

The MIC5321 is a µCap design which enables

operation with very small ceramic output capacitors

for stability, thereby reducing required board space

and component cost. The combination of extremely

low-drop-out voltage, very high power supply

rejection, very low output noise and exceptional

thermal package characteristics makes it ideal for

powering RF application, cellular phone camera

modules, imaging sensors for digital still cameras,

PDAs, MP3 players and WebCam applications.

µCap stable with 1µF ceramic capacitor

Low quiescent current – 150µA

Fast turn-on time – 45µs

Thermal shutdown protection

Current Limit protection

The MIC5321 ULDO™ is available in fixed-output

voltages in the tiny 6-pin 1.6mm x 1.6mm leadless

Thin MLF^®package which is only 2.56mm²in area,

less than 30% the area of the SOT-23, TSOP and

MLF^®3x3 packages. It’s also available in the thin

SOT-23-6 lead package and the standard 6-pin

1.6mm x 1.6mm leadless package. Additional voltage

options are available. For more information, contact

Micrel marketing department.
