Tool/software:

Hi team,

Does TPS736 (ADJ output version) have new gen or can you help recommend other LDO like TPS736 with  reverse current protection but has  lower Iq and higher PSRR?

    Hello Amber,

    Another option would be LP5912 for reverse current and lower IQ, however this device only comes in fixed output. Is this roughly what you were looking for as an alternative?
