MIC5252 Micrel, Inc. MIC5252 150mA High PSRR, Low Noise µCap CMOS LDO General Description The MIC5252 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 MIC5252 provides a very-low-noise output, ideal for RF applications where a clean voltage source is required. The MIC5252 has a high PSRR even at low supply voltages, critical for battery operated electronics. A noise bypass pin is also available for further reduction of output noise. Designed speciﬁcally for handheld and battery-powered devices, the MIC5252 provides a TTL-logic-compatible enable pin. When disabled, power consumption drops nearly to zero.
