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 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-dropout voltage, fast transient response and exceptional thermal package characteristics makes it ideal for portable electronics.
The MIC5320 ULDO™ is available in the thin SOT-23-6 lead package. Additional voltage options are available.
Additional Features
2.3V to 5.5V input voltage range
Ultra-low dropout voltage ULDO: 35mV @ 150mA
Low cost TSOT-23-6 package
Independent enable pins
PSRR: >65dB on each LDO
150mA output current per LDO
µCap stable with 1µF ceramic capacitor
Low quiescent current: 85µA per output
Fast turn-on time: 30µs
Thermal shutdown protection
Current limit protection
