The TPS73xx devices are members of a family of micropower low-dropout (LDO) voltage
regulators.
(TPS7325, TPS7330, TPS7333, TPS7348, and TPS7350) ‡ FB – Adjustable version only (TPS7301)
They are differentiated from the TPS71xx and TPS72xx LDOs by their integrated delayed microprocessor-reset
function. If the precision delayed reset is not required, the TPS71xx and TPS72xx should be cons...
