TPS76733QDR Product Details

TPS76733QDR is part of the TPS767xxQ Fast-Transient-Response 1-A Low-Dropout Linear Regulators.

The TPS767xx features very low quiescent current, which remains virtually constant even with varying loads. Conventional LDO regulators use a pnp pass element, the base current of which is directly proportional to the load current through the regulator (IB = IC/β). 

The TPS767xx uses a PMOS transistor to pass current; because the gate of the PMOS is voltage driven, operating current is low and invariable over the full load range.Another pitfall associated with the pnp-pass element is its tendency to saturate when the device goes into dropout. 

The resulting drop in β forces an increase in IB to maintain the load. During power up, this translates to large start-up currents. Systems with limited supply current may fail to start up. In battery-powered systems, it means rapid battery discharge when the voltage decays below the minimum required for regulation. The TPS767xx quiescent current remains low even when the regulator drops out, eliminating both problems.

The TPS767xx family also features a shutdown mode that places the output in the high-impedance state (essentially equal to the feedback-divider resistance) and reduces quiescent current to 2 µA. If the shutdown feature is not used, EN should be tied to ground.
