MIC5238 Micrel MIC5238 Ultra-Low Quiescent Current, 150mA µCap LDO Regulator General Description Features The MIC5238 is an ultra-low voltage output, 150mA LDO • Ultra-low input voltage range: 1.5V to 6V regulator. Designed to operate in a single supply or dual • Ultra-low output voltage: 1.1V minimum output voltage supply mode, the MIC5238 consumes only 23µA of bias • Low dropout voltage: 310mV at 150mA current, improving efficiency. When operating in the dual • High output accuracy: ±2.0% over temperature supply mode, the efficiency greatly improves as the higher • µCap: stable with ceramic or tantalum capacitors voltage supply is only required to supply the 23µA bias • Excellent line and load regulation specifications current while the output and base drive comes off of the mu
