Microchip | MIC5332-PNYMT-TR

The MIC5332 is a tiny dual low quiescent current LDO ideal for applications that are power sensitive. The MIC5332 integrates two high performance 300 mA LDOs, and a POR generator into a 2 mm x 2 mm 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.

The MIC5332 is a µCap design, operating with very small ceramic output capacitors, which reduces required board space and component cost. It is available in fixed output voltages in a tiny 8-pin 2 mm x 2 mm Thin MLF ® leadless package.

Features:

• 2.3 V to 5.5 V input voltage range
• 300 mA 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 2 mm x 2 mm Thin MLF ® package
• Ultra-low dropout voltage – 120 mV @ 300 mA
• Low output voltage noise – 50 µVrms
• Thermal shutdown protection
• Current limit protection 

Applications:

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