Microchip | MIC5332-G4YMT-TR

The MIC5332 is a tiny dual low quiescent current LDO ideal for applications that are power sensitive. The MIC5332 integrates two high performance 300mA LDOs, and a POR generator into a 2mm x 2mm Thin MLF ® package. This solution occupies the same PC board area of a single SOT 23 package.

The MIC5332 is designed to reject input noise and provide low output noise with fast transient response so as 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 on LDO2
• High PSRR - >65dB on each LDO
• Stable with 1 µF ceramic output capacitors
• Tiny 8-pin 2mm x 2mm 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 receivers
• Portable electronics
