Key Features
- Ultra-low-noise, high-PSRR LDO regulator with 300 mA output current, ideal for powering noise-sensitive RF and precision analog circuits
- Very low dropout voltage of 145 mV maximum and 0.019% load regulation for stable supply in tight headroom battery applications
- Fixed-output SOT-23-5 package with low quiescent current design, extending battery run time in always-on IoT and wearable devices
Applications
The TPS7A20285PDBVR is designed for noise-sensitive analog and RF circuits such as VCOs, PLLs, and precision ADC reference supplies where ultra-low output noise and high PSRR are essential. Its 300 mA current rating and 145 mV dropout make it suitable for powering 2.85 V LTE modem and Wi-Fi module supply rails from a Li-ion battery without a boost converter. The compact SOT-23-5 footprint also makes it a popular choice for handheld medical instruments and wearable biosensor front-ends.

Frequently Asked Questions
What makes the TPS7A20285PDBVR suitable for RF and analog noise-sensitive circuits?
The TPS7A20285PDBVR is specified as ultra-low-noise with high power-supply rejection ratio (PSRR), which attenuates switching noise and ripple from upstream DC-DC converters before it reaches sensitive RF, PLL, or precision ADC circuits. This is critical because noise injected onto a 2.85 V supply rail at frequencies between 100 kHz and 10 MHz can degrade phase noise and SNR by several dB.
What is the maximum dropout voltage of the TPS7A20285PDBVR at full 300 mA output?
The TPS7A20285PDBVR has a maximum dropout voltage of 145 mV at 300 mA output current. This means the device can maintain a regulated 2.85 V output from an input as low as 2.995 V, extending usable battery life by operating close to the Li-ion cell's 3.0 V minimum discharge cutoff.
How does the TPS7A20285PDBVR compare in load regulation performance?
The TPS7A20285PDBVR achieves a maximum load regulation of 0.019%, meaning the output voltage shifts less than 540 µV across the full 0 to 300 mA load range. This tight regulation makes it appropriate for precision reference supply chains and analog front-ends where supply-induced gain errors must stay below 0.05%.
What input voltage range does the TPS7A20285PDBVR require, and is it compatible with 5 V USB power?
The TPS7A20285PDBVR accepts an input voltage from 3.15 V to 6 V, with an absolute maximum of 6.5 V. A standard 5 V USB supply falls within this window, so the device can regulate a stable 2.85 V output directly from USB power for development boards, IoT modules, and wearable devices without additional voltage conversion.
