TPS70950DBVT

The TPS70950DBVT is an Ultralow IQ Wide Input Low-dropout Regulator with reverse current protection designed for power-sensitive applications. A precision band-gap and error amplifier provides 2% accuracy over-temperature. Quiescent current of only 1µA make this device ideal solutions for battery-powered, always-on systems that require very little idle-state power dissipation. This device has thermal-shutdown, current-limit and reverse-current protections for added safety. This regulator can be put into shutdown mode by pulling the EN pin low. The shutdown current in this mode goes down to 150nA, typical. The TPS709 internal current limit helps protect the regulator during fault conditions. During current limit, the output sources a fixed amount of current that is largely independent of output voltage. It uses a PMOS pass transistor to achieve low dropout voltage.
