MICROCHIP TC1302A-DTVMF

The TC1302A/B combines two Low Dropout (LDO) regulators into a single 8-pin MSOP or DFN package. Both regulator outputs feature low dropout voltage, 104 mV @ 300 mA for VOUT1, 150 mV @ 150 mA for VOUT2, low quiescent current consumption, 58 μA each and a typical regulation accuracy of 0.5%. Several fixed-output voltage combinations are available. A reference bypass pin is available to further reduce output noise and improve the power supply rejection ratio of both LDOs. The TC1302A/B is stable over all line and load conditions, with a minimum of 1 μF of ceramic output capacitance, and utilizes a unique compensation scheme to provide fast dynamic response to sudden line voltage and load current changes. Additional features include an overcurrent limit and overtemperature protection that combine to provide a robust design for all load fault conditions.
