TPS7101Q Datasheet (Texas Instruments) - LOW-DROPOUT VOLTAGE REGULATORS

TPS7101Q, LOW-DROPOUT VOLTAGE REGULATORS

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.

TPS7101Q 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.
