Microchip | MIC5333-MNYMT-TR

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 MLF ® 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.

Features:

• 2.3V to 5.5V input voltage range
• 300mA output current per LDO
• Very low quiescent current: 25 µA per LDO
• POR output with programmable delay for each LDO
• High PSRR – >65dB on each LDO
• Stable with 1 µF ceramic output capacitors
• Tiny 10-pin 2.5mm x 2.5mm Thin MLF ® package
• Ultra-low dropout voltage – 120mV @ 300mA
• Low output voltage noise – 50 µVrms
• Thermal shutdown protection
• Current limit protection 

Applications:

• Camera phones
• Mobile phones
• PDAs
• GPS receives
• Portable devices
