Pinout
The TPS73401DDCR is a low-dropout (LDO) linear voltage regulator from Texas Instruments. It comes in a 5-pin SOT-23 package. Here’s a brief overview of its pin functions:
1. IN (Input Voltage): This pin receives the input voltage, which should be higher than the desired output voltage to account for dropout.
2. GND (Ground): The ground pin is the common return path for input and output voltages.
3. NR/FB (Noise Reduction/Feedback): This pin is used for noise reduction when connecting a capacitor to ground. In adjustable version, it serves as the feedback pin.
4. OUT (Output Voltage): This pin delivers the regulated output voltage.
5. EN (Enable): The enable pin is used to turn the LDO on or off. Pulling this pin high enables the regulator, whereas pulling it low disables the output.
This LDO is designed for high-performance applications, offering low noise, low quiescent current, and high power-supply rejection ratio (PSRR), making it suitable for powering sensitive analog circuits.
