The TPS72xx family of micro‑power low‑dropout (LDO) voltage regulators offers very low dropout voltage, low quiescent current, and compact SOIC/TSSOP packages. These devices are suited for portable designs where board space and battery life are critical.
The document provides detailed electrical characteristics, absolute maximum ratings, recommended operating conditions, typical application circuits, and a full list of orderable device packages.
| Maximum Dropout Voltage | <85 mV at I_O = 100 mA (TPS7250) |
|---|---|
| Quiescent Current (active mode) | 180 mA typ |
| Sleep‑Mode Current | 0.5 mA max |
| Maximum Continuous Power Dissipation (PW package) | 1175 mW at TA = 25 °C |
The dropout voltage is less than 85 mV at a load current of 100 mA for the TPS7250 device.
They draw a typical quiescent current of 180 mA, independent of load.
In sleep mode the regulators consume a maximum of 0.5 mA.
