What are the key features of TPS73701DRVR?
- Ultra-low 130 mV typical dropout voltage at 1 A output current extends battery life in portable 3.3 V and 5 V regulated rails
- Adjustable output from 1.2 V to 5.0 V via two external resistors covers the most common logic and analog supply voltages in a single SKU
- Integrated reverse current protection prevents back-feed damage during power sequencing in multi-rail systems
What is TPS73701DRVR used for?
The TPS73701DRVR is suited for post-regulation of switching supplies in IoT modules, wireless SoC boards, and portable instruments where a clean, low-noise rail is needed alongside a noisy DC-DC converter output. Its 130 mV typical dropout and 1 A continuous output make it a practical choice for powering FPGAs, DSPs, and RF transceivers from Li-Ion or 5 V USB sources. The 6-pin WSON package keeps PCB area under 4 mm², supporting dense multi-rail power trees on compact embedded boards.

Frequently Asked Questions
What is the dropout voltage of the TPS73701DRVR at full load, and why does it matter for battery-powered designs?
The TPS73701DRVR achieves a typical dropout of only 130 mV at 1 A, meaning a 3.3 V rail stays regulated down to a 3.43 V input, allowing designs to extract more usable capacity from a Li-Ion cell before the regulator drops out of regulation.
What output voltage range can be set with the TPS73701DRVR, and how is it configured?
The output is adjustable from 1.2 V to 5.0 V using two external resistors connected to the ADJ pin according to the standard voltage divider formula, with a reference voltage of 1.21 V, making it straightforward to target 1.8 V, 2.5 V, 3.3 V, or 5.0 V rails with standard 1% resistors.
How does the reverse current protection in the TPS73701DRVR protect multi-rail power systems?
The integrated reverse current protection blocks current from flowing from the output back into the input during power-down sequencing or when the input supply collapses below the output, preventing latch-up or unexpected powering of upstream components through the regulator path in systems with 5 V and 3.3 V rails.
What is the input voltage range of the TPS73701DRVR, and can it run directly from a 5 V USB supply?
The TPS73701DRVR accepts input voltages from 2.2 V to 5.5 V, which comfortably covers a 5 V USB VBUS rail (nominal 4.75 V to 5.25 V), making it a direct fit for USB-powered designs that need a clean 3.3 V or 1.8 V analog or RF supply.
How does the TPS73701DRVR compare to the TPS737 fixed-voltage variants for multi-product platforms?
Unlike TPS73733 or TPS73718 fixed-output variants, the TPS73701DRVR uses external resistors to set any output between 1.2 V and 5.0 V, allowing a single PCB design and one stock-keeping unit to cover multiple product variants differing only by 1% resistor values, reducing procurement complexity and buffer stock.
