Applications
TPS78225DRVTG4 provides a clean, fixed 2.5 V rail for precision analog ICs, RF transceivers, and ADC reference supplies in battery-powered devices and IoT sensor nodes where low dropout and low noise are critical. Its 2.2 V minimum input allows operation from a single lithium cell near end-of-discharge or from low headroom 3.3 V logic supplies. The compact 6-pin WSON package suits wearable devices, medical sensors, and wireless modules where PCB space is tightly constrained.

Frequently Asked Questions
What is the dropout voltage of TPS78225DRVTG4, and why does it matter for battery applications?
TPS78225DRVTG4 has a typical dropout voltage of 0.13 V and a maximum of 0.25 V at 150 mA output current. This low dropout means the device can maintain a regulated 2.5 V output from an input as low as 2.63 V, extending usable battery runtime in lithium-ion or alkaline-powered designs before the output falls out of regulation.
How accurate is the output regulation of TPS78225DRVTG4 over input voltage changes?
TPS78225DRVTG4 achieves a maximum line regulation of 0.025%, meaning the output voltage changes by no more than 0.625 mV for a full swing across the 2.2 V to 5.5 V input range. This level of precision is suitable for powering reference voltages in 12-bit or 16-bit ADC circuits where supply variation directly affects measurement accuracy.
For a compact wireless sensor node, how small is the TPS78225DRVTG4 footprint?
TPS78225DRVTG4 uses the 6-pin WSON package with exposed thermal pad, measuring approximately 1.5 mm x 1.5 mm. This is among the smallest LDO package options for 150 mA regulators, enabling placement directly under or adjacent to the MCU or RF IC it powers on highly dense sensor node PCBs where standard SOT-23 or SOT-89 packages would consume too much area.
Can TPS78225DRVTG4 power an RF transceiver from a 3.3 V system rail?
Yes, TPS78225DRVTG4 accepts inputs up to 5.5 V and has a typical dropout of only 0.13 V, so a 3.3 V system rail provides 0.8 V of headroom above the 2.5 V output, well above the maximum 0.25 V dropout. The low-noise output and tight 0.025% line regulation make it suitable for sub-GHz and 2.4 GHz RF transceiver supply rails where power supply noise degrades receiver sensitivity.
