Pinout
The TPS77033DBVR is a low-dropout (LDO) voltage regulator from Texas Instruments. It comes in a 5-pin SOT-23 package. The primary function of this device is to provide a fixed 3.3V output with a maximum output current of 50 mA, making it suitable for battery-powered applications due to its low quiescent current.
Here is a brief description of each pin:
1. IN: This is the input pin where the unregulated input voltage is supplied.
2. GND: Ground pin for the LDO.
3. OUT: This is the regulated output pin that provides the 3.3V output voltage.
4. NR/FB: Noise reduction or feedback pin. Connecting a capacitor here can reduce output noise; it can also be used for feedback in adjustable versions.
5. EN: Enable pin used to turn the regulator on or off. When pulled high, the regulator is enabled; pulling it low disables the output.
These features make the TPS77033DBVR ideal for low-power and portable applications.
