TPS7133Q Datasheet | Texas Instruments

ion The TPS71xx integrated circuits are a family of micropower low-dropout (LDO) voltage regulators. An order of magnitude reduction in dropout voltage and quiescent current over conventional LDO performance is achieved by replacing the typical pnp pass transistor with a PMOS device.

Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and remains independent of output loading (typically 285 µA over the full range of output current, 0 m A to 500 m A). These two key specifications yield a significant improvement in operating life for battery-powered systems. The LDO family also Features a sleep mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to 0.5 µA maximum at TJ = 25°C.
