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

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.

found on Micrel’s web site at www.micrel.com.

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.
