MIC5232-2.8YD5-TR Microchip

MIC5232 10mA Ultra-Low Quiescent Current Cap LDO Features Input voltage range: 2.7V to 7.0V General Description A operating current Ultra-low Iq: Only 1.8 The MIC5232 is an ultra-low quiescent current, low- Stable with 0.47F ceramic output capacitor dropout linear regulator that is capable of operating Low dropout voltage of 100mV 10mA from a single-cell lithium ion battery. Consuming only Reverse Battery Protection 1.8A of quiescent current while operating, the MIC5232 is ideal for stand-by applications like High output accuracy: powering real-time clocks or memory in battery +2.0% initial accuracy operated electronics. +3.0% over temperature Logic-Level Enable Input The MIC5232 is capable of providing 10mA of output current and has low output noise, providing a small, Miniature 6-pin 2mm x 2mm MLF package efficient solution ideal for any keep-alive application. Lead-Free Thin SOT-23-5 Package This includes reverse current protection, keeping Tight Load and Line Regulation reverse leakage (V > V ) down to 20nA. OUT IN Applications The MIC5232 is a Cap design, operating with very small ceramic output capacitors for stability, reduction Real-Time Clock Power Supply of required board space and component cost. Stand-by Power Supply SRAM Memory Back-up Supply The MIC5232 is available in fixed output voltages in the miniature 6-pin 2mm x 2mm MLF package and Cellular Telephones and Notebook Computers thin SOT-23-5 package with an operating junction temperature range of -40C to 125C.
