The TPS71xx integrated circuits are a family of micropower low-dropout (LDO) voltage regulators. They achieve an order of magnitude reduction in dropout voltage and quiescent current compared to conventional LDO performance by replacing the typical pnp pass transistor with a PMOS device. These products feature very low dropout voltage, extremely low quiescent current, extremely low sleep-state current, and a wide output current range.
The TPS71xx family is a series of micropower low-dropout (LDO) voltage regulators that use a PMOS pass element to achieve very low dropout voltage and quiescent current. The family includes fixed‑output versions (3.3 V, 4.85 V, 5 V) and an adjustable version programmable from 1.2 V to 9.75 V.
The document provides detailed electrical characteristics, absolute‑maximum ratings, package options (PDIP, SO, TSSOP), thermal information, and ordering status. It also describes typical application circuits and pin configurations for the various device variants.
| Maximum dropout voltage | 32 mV at 100 mA (TPS7150) |
|---|---|
| Quiescent current (active mode) | 285 µA typical |
| Sleep‑mode current | 0.5 µA max |
| Output current range | 0 mA to 500 mA |
| Available packages | PDIP (8‑pin), SO (8‑pin), TSSOP (20‑pin) |
The maximum dropout voltage is 32 mV at an output current of 100 mA for the TPS7150 device.
The typical quiescent current is 285 µA, independent of load.
In sleep mode the regulator draws a maximum of 0.5 µA.
Fixed‑output versions are available at 3.3 V, 4.85 V, and 5 V, and an adjustable version can be programmed from 1.2 V to 9.75 V.
