General Description

The MIC5335 is a high current density, dual Ultra Low

Dropout (ULDO™) linear regulator. The MIC5335 is

ideally suited for portable electronics which demand

overall high performance in a very small form factor.

The MIC5335 is offered in the ultra small 1.6mm x

1.6mm x 0.55mm 6-ld Thin MLF

only 2.56mm

2

in area. The MIC5335 delivers

exceptional

thermal

performance

for

those

applications that demand higher power dissipation in

a very small foot print. In addition, the MIC5335

integrates two high performance 300mA LDOs with

independent enable functions and offers high PSRR

eliminating the need for a bypass capacitor.

The MIC5335 is a µCap design which enables

operation with very small output capacitors for

stability, thereby reducing required board space and

component cost.

The MIC5335 is available in fixed-output voltages.

Additional

voltages

are

available.
