Applications
The TPS78825DBVTG4 is ideal for powering microcontrollers, sensors, and low-power wireless modules in battery-operated IoT devices and wearables that require a stable 2.5V rail from a single-cell Li-ion source. It is also used in portable test instruments and handheld medical devices where the 5-pin SOT-23 footprint conserves board area and the low 0.3V dropout extends battery runtime. Its tight output accuracy suits precision analog front-ends and ADC reference supply circuits operating from 3.5V to 10V input rails.

Frequently Asked Questions
What is the dropout voltage of the TPS78825DBVTG4 and how does it affect battery life in portable designs?
The TPS78825DBVTG4 has a maximum dropout voltage of 0.3V at full 150mA load. This means it continues regulating a stable 2.5V output even when a Li-ion battery discharges down to approximately 2.8V, extending usable battery runtime by 15-20% compared to regulators with 1V dropout at the same current level.
Which low-power microcontroller and sensor supply rails can the TPS78825DBVTG4 support at 150mA from a 5V USB source?
Operating from a 5V USB input, the TPS78825DBVTG4 delivers a fixed 2.5V output at up to 150mA, which is sufficient to power ARM Cortex-M0 microcontrollers drawing 20-50mA plus MEMS sensors at 5-10mA each. The 0.3V dropout and 0.016% line regulation ensure a clean 2.5V rail even under rapidly switching digital loads.
How does the SOT-23 5-pin package of the TPS78825DBVTG4 compare to larger LDO packages for space-constrained PCBs?
The 5-pin SOT-23 package occupies approximately 8.1 mm² of PCB footprint, roughly 4 times smaller than a SOT-89 or TO-252 package. This compact form factor allows placement of the TPS78825DBVTG4 directly adjacent to the load IC, reducing input and output decoupling trace lengths to under 5mm for improved high-frequency noise rejection.
When is TPS78825DBVTG4 a better choice than an adjustable LDO for a fixed 2.5V rail design?
For fixed 2.5V rails, the TPS78825DBVTG4 eliminates the 2 external feedback resistors required by adjustable LDOs, reducing component count and resistor divider noise contribution. The internal precision reference achieves tighter output tolerance at 2.5V ±1.5% without any trim, simplifying BOM and PCB layout in production volumes above 1,000 units.
