† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values are with respect to GND.
2. Absolute negative voltage on these terminal should not be below 0.5 V.
3. RqJA must be less than 55°C/W, typically achieved with two square inches of copper printed circuit board area connected to the GND
terminals for heat dissipation or equivalent.


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 TPPM0301 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.
