TPPM0301DR-TPPM0301DRG4
Single-Output 400mA, 3.3V Low-Dropout (LDO) Regulator with Selectable 3.3V or Dual 5V Input
400-mA Load Current Capability With 5-V or3.3-V Input Source Low rDS(on) Auxiliary Switch Thermally Enhanced Packaging Concept
for Efficient Heat Management


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.
