MIC5392/3

High-Performance Dual 150mA LDO

Revision 1.2

General Description

Features

The MIC5392/3 is a tiny dual low-dropout linear regulator

ideally suited for portable electronics. It is ideal for general

purpose/digital applications which require high-power

supply ripple rejection (PSRR) >60dB, eliminating the need

for a bypass capacitor and providing two enable pins for

maximum flexibility. The MIC5392/3 integrates two high-

performance; 150mA LDOs into a tiny 6-pin, 1.2mm x

1.2mm leadless DFN package, which provides exceptional

thermal package characteristics.

• 2.5V to 5.5V input voltage range

• Two 150mA output current LDOs

• High output accuracy

− ±2% initial accuracy

• Low quiescent current (32µA per LDO)

• Stable with 1µF ceramic output capacitors

• Independent enable pins

• Low dropout voltage (155mV at 150mA)

• Thermal-shutdown protection

The MIC5392/3 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 low-drop-out voltage, high power

supply rejection and exceptional thermal package

characteristics makes it ideal for powering mobile phones

camera modules, image sensors, PDAs, MP3 players and

audio codec power applications.

• Current-limit protection

• Internal 25Ω output discharge circuit (MIC5393)

• 1.2mm × 1.2mm Extra Thin DFN package (H ≤ 0.4mm)

• 1.2mm × 1.2mm Thin DFN package

Applications

The MIC5392/3 is available in fixed-output voltages in the

tiny 6-pin 1.2mm x 1.2mm leadless DFN package which is

only 1.44mm²in area. Additional voltage options are

available.

• Smart phones

• Tablet PCs

• GPS, PMP, PDAs, and handhelds

• Audio codec power

• Portable electronics

• 5V systems
