MIC5319-2.7YD5-TR Microchip

MIC5319 500mA Cap Ultra-Low Dropout High PSRR LDO Regulator General Description Features The MIC5319 is a high-performance, 500mA LDO Ultra-low dropout voltage 200mV @ 500mA regulator, offering extremely high PSRR and very-low Input voltage range: 2.5 to 5.5V noise while consuming low ground current. Stable with ceramic output capacitor Ideal for battery-operated applications, the MIC5319 Low output noise: 40Vrms features 1% accuracy, extremely low-dropout voltage Low quiescent current of 90A total (200mV @ 500mA), and low ground current at light load (typically 90A). Equipped with a logic-compatible enable High PSRR, up to 70dB @1kHz pin, the MIC5319 can be put into a zero-off-mode current Fast turn-on-time: 40s typical state, drawing no current when disabled. High-output accuracy: The MIC5319 is a Cap design operating with very-small 1.0% initial accuracy ceramic output capacitors for stability, thereby reducing 2.0% over temperature required board space and component cost. Thermal-shutdown protection The MIC5319 is available in fixed-output voltages and Current-limit protection adjustable output voltages in the super-compact 2mm x Logic-controlled Enable 2mm MLF leadless package and thin SOT-23-5 package. Tiny 2mm x 2mm MLF package, 500mA continuous Data sheets and support documentation can be found on Thin SOT-23-5 package, 500mA peak Micrels web site at www.micrel.com.
