MIC5305-3.3YD5-TR Microchip

MIC5305 150mA Cap Ultra-Low Dropout LDO Regulator General Description Features The MIC5305 is a high-performance, 150mA LDO regula- Ultra-low dropout voltage of 60mV 150mA tor, offering extremely high PSRR and very low noise while Input voltage range: 2.25 to 5.5V consuming low ground current. Stable with ceramic output capacitor Ideal for battery-operated applications, the MIC5305 150mA guaranteed output current features 1% accuracy, extremely low-dropout voltage Low output noise 20Vrms (60mV 150mA), and low ground current at light load Low quiescent current of 90A total (typically 90A). Equipped with a logic-compatible enable High PSRR, up to 85dB 1kHz pin, the MIC5305 can be put into a zero-off-mode current Less than 30s turn-on time w/C = 0.01F BYP state, drawing no current when disabled. High output accuracy: The MIC5305 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 Current limit protection The MIC5305 is available in xed output voltages and Tiny 6-pin 2mm 2mm MLF package adjustable output voltages in the super-compact 6-pin Ultra-Thin 6-pin 2mm 2mm Thin MLF package 2mm 2mm MLF leadless package, our new ultra-thin 6-pin 2mm 2mm Thin MLF and thin SOT-23-5 package.
