MIC5255 150mA Low Noise µCap CMOS LDO The MIC5255 is an efficient, precise CMOS voltage regulator optimized for ultra-low-noise applications. It offers 1% initial accuracy, extremely-low dropout voltage 135mV at 150mA and low ground current typically 90µA . The MIC5255 provides a very-low-noise output, ideal for RF applications where a clean voltage source is required. A noise bypass pin is also available for further reduction of output noise. Designed for handheld and battery-powered devices, the MIC5255 provides a TTL-logic-compatible enable pin. When disabled, power consumption drops nearly to zero. The MIC5255 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in handheld wireless devices. • Input voltage range 2.7V to 6.0V • Thin SOT package 1mm height SOT-23-5 • Ultra-low output noise 30µV rms • Stability with ceramic output capacitors • Ultra-low dropout 135mV 150mA • High output accuracy: initial accuracy over temperature • Low quiescent current 90µA • Tight load and line regulation • TTL-Logic-controlled enable input • “Zero” off-mode current • Thermal shutdown and current limit protection Key features include current limit, thermal shutdown, faster transient response, and an active clamp to speed up device turn-off.
