MIC5253-3.0YC5/Micrel，100mA Low NoiseµCap Teeny™ LD.100年马英九低NoiseµCap小小的™LD

General DescriptionThe MIC5253 is an efficient, CMOS voltage regulator opti-mized for ultra-low-noise applications. It offers 1.5% initialaccuracy, extremely low dropout voltage (165mV at 100mA),and low ground current (typically 95µA at full load). TheMIC5253 provides a very low noise output, ideal for RFapplications where a clean voltage source is required. Anoise bypass pin is also available for further reduction ofoutput noise.Designed specifically for handheld and battery-powered de-vices, the MIC5253 provides a TTL-logic-compatible enablepin. When disabled, power consumption drops nearly to zero.The MIC5253 also works with low-ESR ceramic capacitors,reducing the amount of board space necessary for powerapplications, critical in handheld wireless devices.Available in the Teeny™ SC-70-5 package, the MIC5253offers a wide range of output voltages. Key features includecurrent limit, thermal shutdown, faster transient response,and an active clamp to speed up device turn-off。
