MIC5203-3.3YM5-TR

MIC5203-3.3YM5-TR is a µCap 80mA linear voltage regulator with very low dropout voltage (typically 20mV at light loads and 300mV at 80mA) and extremely low ground current (225µA at 20mA output), offering better than 3% initial accuracy with a logic-compatible enable input. The µCap regulator design is optimized to work with low-value, low-cost ceramic capacitors. The outputs typically require only 0.47µF of output capacitance for stability. Specifically designed for handheld, battery-powered devices, the MIC5203 can be controlled by a CMOS or TTL-compatible logic signal. When disabled, power consumption drops nearly to zero. If on-off control is not required, the enable pin may be tied to the input for 3-terminal operation. Applications include cellular telephones, laptops, notebooks, palmtop computers, battery-powered equipment, barcode scanners, SMPS post-regulators, DC/DC modules, and high-efficiency linear power supplies.
