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-drop-out 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 2.56mm
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 and the standard 6-pin
1.6mm x 1.6mm leadless 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.
3. The maximum allowable power dissipation of any T

. 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.
