MIC5320
High-Performance Dual 150mA
µCap ULDO™
General Description
Features
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.

Current-limit protection
Applications
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
