MIC5320-1.8/1.5YD6

Manufacturer Part Number
MIC5320-1.8/1.5YD6
Description
Dual, High Performance 150mA uCap ULDO
Manufacturer
MICREL [Micrel Semiconductor]
Datasheet
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
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
than 30% the area of the SOT-23, TSOP and MLF
3x3 packages. It’s also available in the thin SOT-23-6
lead
available. For more information, contact Micrel
