MIC5230 Micrel MIC5230 10mA Microcurrent Voltage Regulator Preliminary Information General Description Features The MIC5230 is a family of efficient linear voltage regulators • Extremely low quiescent current with a very low dropout voltage (typically 20mV at light loads • Tiny SOT-23-5 surface mount package and 132mV at 10mA), and an extremely low ground current • Wide selection of output voltages (1µA typical, across the full output current range). • Guaranteed 10mA output • Low dropout voltage Designed especially for hand-held battery powered devices, • No output capacitor needed the MIC5230 offers better than 3% initial accuracy. This • Insensitive to output capacitor ESR regulator’s ability to also sink current improves regulation • Tight load and line regulation under
