What are the key features of TPS70933DBVR?

  • Ultra-wide 4.3 V to 30 V input range supporting 5 V, 12 V, and 24 V industrial supply rails
  • Built-in reverse current protection preventing battery drain when input falls below output
  • Ultra-low quiescent current minimizing standby power loss in always-on IoT and metering nodes

What is TPS70933DBVR used for?

The TPS70933DBVR is well suited for industrial sensors, smart meters, and factory automation nodes that operate from 12 V or 24 V bus supplies requiring a local regulated rail. Its reverse current protection prevents current backflow from the output reservoir capacitor when the input is disconnected, critical for battery-backed circuits. Always-on IoT edge devices and wireless alarm systems benefit from its ultra-low Iq and wide input tolerance across varying supply conditions.

Frequently Asked Questions

How does the reverse current protection in TPS70933DBVR safeguard battery-backed circuits?

TPS70933DBVR's reverse current protection blocks current from flowing from the output back to the input when the supply voltage collapses or is disconnected. This prevents discharging a backup battery through the regulator's parasitic diode path, preserving charge for up to several additional hours in smart meter and alarm panel designs operating from a 3.3 V or 5 V output rail.

Which industrial supply voltages can TPS70933DBVR accept without additional pre-regulation?

TPS70933DBVR accepts input from 4.3 V minimum to 30 V maximum, directly accommodating 5 V logic rails, 12 V automotive and industrial bus voltages, and 24 V factory automation supplies, eliminating the need for a pre-regulator stage and reducing BOM cost by 2-3 components.

What dropout voltage should designers budget for TPS70933DBVR at full 150 mA load?

At 150 mA full load, TPS70933DBVR exhibits a maximum dropout of 1.4 V, so the input must exceed the desired output voltage by at least 1.4 V to maintain regulation. At lighter loads of 10 mA or less, the typical dropout drops to approximately 30 mV, significantly relaxing input headroom requirements.
