MIC5320
Dual, High Performance 150mA µCap ULDO™
General Description
The MIC5320 is a tiny Dual Ultra Low-Dropout
(ULDO™) linear regulator ideally suited for portable
electronics. It is ideal for general purpose/ digital
applications which require high power supply ripple
rejection (PSRR) >65dB, eliminating the need for a
bypass capacitor and providing two enable pins for
maximum flexibility. The MIC5320 integrates two high-
performance; 150mA ULDOs into a tiny 6-pin 1.6mm x
1.6mm leadless 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-drop-out voltage, high power supply rejection and
exceptional thermal package characteristics makes it
ideal for powering cellular phone camera modules,
imaging sensors for digital still cameras, PDAs, MP3
players and WebCam applications.
The MIC5320 ULDO™ is available in fixed-output
voltages in the tiny 6-pin 1.6mm x 1.6mm leadless
MLF
®
package which is only 2.56mm
2
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. Additional voltage options are
available. For more information, contact Micrel
marketing department.

1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.

. Exceeding the maximum allowable
power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
4. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
5. Specification for packaged product only.
6. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal V
OUT
. For outputs below 2.3V,
the dropout voltage is the input-to-output differential with the minimum input voltage 2.3V.
