description

The TPPM0301 is a low-dropout regulator with auxiliary power management that provides a constant 3.3-V

supply at the output capable of driving a 400-mA load.

The TPPM0301 provides a regulated power output for systems that have multiple input sources and require a

constant voltage source with a low-dropout voltage. This is a single output, multiple input intelligent power

source selection device with a low-dropout regulator for either 5VCC or 5VAUX inputs, and a low- resistance

bypass switch for the 3.3VAUX input.

Transitions may occur from one input supply to another without generating a glitch, outside of the specification

range, on the 3.3-V output. The device has an incorporated reverse blocking scheme to prevent excess leakage

from the input terminals in the event that the output voltage is greater than the input voltage.

The input voltage is prioritized in the following order: 5VCC, 5VAUX, and 3.3VAUX.

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

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
