What are the key features of TPS72116DBVTG4?
- 150 mA output current with ultra-low 200 mV dropout voltage, enabling efficient 1.6 V regulation from 1.8 V input rails
- Fixed 1.6 V output with ±3% accuracy across input voltage range of 1.8 V to 5.5 V, suited for precise core-voltage supply
- 5-pin SOT-23 package with minimal external components required, simplifying layout in space-constrained portable designs
What is TPS72116DBVTG4 used for?
The TPS72116DBVTG4 is used to generate stable 1.6 V core supplies for FPGAs, DSPs, and low-power microcontrollers that require a tightly regulated voltage from a higher input rail. Its 200 mV low dropout characteristic allows operation from a 1.8 V supply, making it an excellent post-regulator in battery-powered and energy-harvesting systems. The compact SOT-23 footprint suits wearable electronics, wireless sensor nodes, and portable medical instruments.

Frequently Asked Questions
What is the minimum input voltage needed to maintain the 1.6 V output on the TPS72116DBVTG4 at full load?
At maximum load of 150 mA, the TPS72116DBVTG4 requires an input voltage of at least 1.8 V, since its dropout voltage is 200 mV. This means the part can regulate 1.6 V from a 1.8 V lithium-ion battery end-of-life rail, extending usable battery capacity in portable devices where every millivolt of headroom matters.
How does TPS72116DBVTG4 compare to TPS721 variants with different output voltages for a 3.3 V to 1.6 V step-down application?
For a 3.3 V input supplying a 1.6 V load, the TPS72116DBVTG4 dissipates (3.3 V − 1.6 V) × 150 mA = 255 mW maximum in the SOT-23 package. Other TPS721 variants with higher output voltages such as 1.8 V or 2.5 V would dissipate less heat, so the 1.6 V version is best chosen when downstream logic specifically requires the 1.6 V rail and thermal budgeting is acceptable.
What external components are required for a complete TPS72116DBVTG4 application circuit?
A minimal TPS72116DBVTG4 circuit needs only a 100 nF input bypass capacitor and a 1 µF output capacitor to maintain stability across the 1.8 V to 5.5 V input range. The EN pin can be tied directly to VIN for always-on operation, or driven by a logic signal for power sequencing. This 5-pin solution reduces BOM to 3 passive components.
