MIC5246 Micrel MIC5246 150mA µCap CMOS LDO Regulator Final Information The MIC5246 is an efficient, precise CMOS voltage regulator optimized for low-noise applications. The MIC5246 offers better than 1% initial accuracy, extremely-low-dropout voltage typically 150mV at 150mA and constant ground current typically 85µA over load The MIC5246 features an error flag that indicates an output fault condition such as overcurrent, thermal shutdown and dropout. The MIC5246 provides a very low noise output, ideal for RF applications where quiet voltage sources are required. Designed specifically for hand-held and battery-powered devices, the MIC5246 provides a TTL-logic-compatible enable pin. When disabled, power consumption drops nearly to zero. The MIC5246 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. Key features include current limit, thermal shutdown, a pushpull output for faster transient response, and an active clamp to speed up device turnoff.
