Description
The TC1301A/B bines two Low Dropout (LDO) regulators and a microcontroller RESET function into a single 8-pin MSOP or DFN package. Both regulator outputs feature low dropout voltage, 104 m V @ 300 m A for VOUT1, 150 m V @ 150 m A for VOUT2, low quiescent current consumption, 58 µA each and a typical regulation accuracy of 0.5%. Several fixedoutput voltage and detector voltage binations are available. A reference bypass pin is available to further reduce output noise and improve the power supply rejection ratio of both LDOs.
The TC1301A/B is stable over all line and...
