Key Features
- 50 mA output current with ultra-low 85 µA quiescent current for extended battery life in portable designs
- Fixed 1.5 V output with 1.2 V typical dropout and 2.7 V to 10 V input range in a tiny 5-pin SOT-23 package
- Excellent load regulation of 0.008% max and line regulation of 0.011% max for stable rail in noise-sensitive analog circuits
Applications
The TPS77015DBVTG4 is designed for battery-powered and always-on embedded systems where minimizing quiescent current is critical, such as IoT sensor nodes, handheld meters, and wearable devices. Its fixed 1.5 V output and 50 mA capability make it suitable for powering low-voltage microcontrollers, RF modules, and memory ICs from a single-cell Li-ion or dual-cell alkaline source. The tiny SOT-23 footprint conserves board space on space-constrained portable PCBs.

Frequently Asked Questions
For a single-cell Li-ion battery circuit, what input voltage range does the TPS77015DBVTG4 support and how much headroom is needed above the 1.5 V output?
The TPS77015DBVTG4 accepts input voltages from 2.7 V to 10 V, so it comfortably operates from a single-cell Li-ion battery discharging between 3.0 V and 4.2 V. With a typical dropout voltage of 1.2 V, the minimum usable battery voltage before dropout is approximately 2.7 V, giving the circuit full regulation down to near the cell's end-of-discharge cutoff.
How does the 85 µA quiescent current of the TPS77015DBVTG4 affect battery life in a sleep-mode IoT sensor node?
At 85 µA quiescent current, the TPS77015DBVTG4 draws only 85 µA even when the load sleeps at near-zero current. On a 1000 mAh AAA alkaline pair in a duty-cycled node active for 1% of the time, this quiescent draw adds less than 12 mAh per day of idle drain — extending the maintenance interval to over 2 years compared to LDOs with 1 mA or higher quiescent current.
In what situations is TPS77015DBVTG4 a better fit than a switching converter for a 1.5 V power rail?
The TPS77015DBVTG4 is preferred over a switching converter when the 1.5 V load current stays below 50 mA and low output noise is more important than efficiency — for example, in ADC reference supplies, audio codec rails, or RF front-end bias circuits where a buck converter's switching noise above 300 kHz would degrade SNR by several dB. The SOT-23 also occupies under 10 mm² versus the larger inductor footprint required by a switching regulator.
