TPPM0301 单输出 400mA 3.3V 低压降 (LDO) 稳压器，具有可选 3.3V 或双 5V 输入
TPPM0301 描述
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
