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.
