The MIC5333 is a tiny dual low quiescent current LDO ideal for applications that are power sensitive. The MIC5333 integrates two high performance, 300mA LDOs and a POR generator for each LDO into a 2.5mm x 2.5mm Thin package, which occupies less PC board area than a single SOT-23 package.
The MIC5333 is designed to reject input noise and provide low output noise with fast transient response to respond to any load change quickly even though it is a low quiescent current part. This combination of PSRR, low noise and transient response along with low power consumption makes for a very high performance, yet general purpose product.
The MIC5333 is a µCap design, operating with very small ceramic output capacitors, which reduces required board space and component cost; and it is available in fixed output voltages in the tiny 10-pin 2.5mm x 2.5mm Thin leadless package.
Additional Features
2.3V to 5.5V input voltage range
300mA output current per LDO
Very low quiescent current: 25µA per LDO
POR output with programmable delay for each LDO
High PSRR: >65dB on each LDO
Stable with 1µF ceramic output capacitors
Ultra-low dropout voltage: 120mV @ 300mA
Low output voltage noise: 50 µVrms
Thermal shutdown protection
Current limit protection
