High-Performance Dual 150mA µCap ULDO™

Micrel 

MIC5320

High-Performance Dual 150mA

µCap ULDO™

General Description

The MIC5320 is a tiny Dual Ultra Low-Dropout

(ULDO™) linear regulator ideally suited for portable

electronics. It’s ideal for today’s most demanding

ultra-thin portable applications including mobile

phones, camera modules, imaging sensors for digital

still and video cameras, PDAs, portable media players

(PMP) and PC cameras. The MIC5320 integrates two

high-performance, 150mA ULDOs into a tiny 6-pin

1.6mm x 1.6mm leadless Thin MLF® package, which

provides exceptional thermal package characteristics.

The MIC5320 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-dropout voltage, fast transient response and

exceptional thermal package characteristics makes it

ideal for portable electronics.

The MIC5320 ULDO™ is available in fixed-output

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

Thin MLF® package which is only 2.56mm2 in 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.
