General Description

Thermal The TPS71Hxx integrated circuits are a family of Pad micropower low-dropout (LDO) voltage regula- tors.

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.

Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (maximum of 32 mV at an output current of NC − No internal connection † SENSE − Fixed voltage options only (TPS71H33, TPS71H48, and TPS71H50) ‡ FB − Adjustable version only (TPS71H01) 100 mA for the TPS71H50) and is directly proportional to the output current (see Figure 1).

Key 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. Please be aware that an important notice concerning availability, standard warranty, and use in critical.
