MIC5321
Dual, High Performance
150mA Cap ULDO
General Description Features
The MIC5321 is a tiny Dual Ultra Low-Dropout 2.3V to 5.5V input voltage range
(ULDO) linear regulator ideally suited for those
Ultra-low dropout voltage ULDO 35mV @
applications that require high PSRR because it
150mA
provides a bypass pin for those noise sensitive
Tiny 6-pin 1.6mm x 1.6mm Thin MLF leadless
portable electronics. The MIC5321 integrates two
package
high-performance; 150mA ULDOs into a very compact
Low cost TSOT-23-6 package
1.6mm x 1.6mm leadless Thin MLF package that
provides exceptional thermal package characteristics. Bypass pin for improved noise performance
High PSRR >75dB on each LDO
The MIC5321 is a Cap design which enables
operation with very small ceramic output capacitors
Ultra low noise output - > 30Vrms
for stability, thereby reducing required board space
Dual 150mA outputs
and component cost. The combination of extremely
Cap stable with 1F ceramic capacitor
low-drop-out voltage, very high power supply
Low quiescent current 150A
rejection, very low output noise and exceptional
thermal package characteristics makes it ideal for
Fast turn-on time 45s
powering RF application, cellular phone camera
Thermal shutdown protection
modules, imaging sensors for digital still cameras,
Current Limit protection
PDAs, MP3 players and WebCam applications.
The MIC5321 ULDO is available in fixed-output
