MIC5331-PPYMT-TR Microchip

MIC5331 Micro-Power High Performance Dual 300 mA ULDO Features General Description 2.3V to 5.5V Input Voltage Range The MIC5331 is a tiny dual low quiescent current LDO ideal for applications that are power sensitive. The 300 mA Output Current per LDO MIC5331 integrates two high performance, 300mA Low Quiescent Current: 25 A per LDO LDOs into a tiny 2 mm x 2 mm Thin DFN package, High PSRR: >65 dB on Each LDO which occupies less PC board area than a single Stable with 1 F Ceramic Output Capacitors SOT-23 package. Tiny 8-pin 2 mm x 2 mm Thin DFN Package The MIC5331 is designed to reject input noise and Ultra-Low Dropout Voltage: 120 mV 300 mA provide low output noise with fast transient response to Low Output Voltage Noise: 50 V any load change quickly even though it is a low RMS quiescent current part. This combination of PSRR, low Thermal Shutdown Protection noise and transient response along with low power Current-Limit Protection consumption makes for a very high performance, yet Applications general purpose product. Camera Phones The MIC5331 is a Cap design, operating with very Mobile Phones small ceramic output capacitors, which reduces required board space and component cost and it is PDAs available in fixed output voltages in the tiny 8-pin 2 mm GPS Receivers x 2 mm Thin DFN lead-less package.
