Pinout
The TPS79133DBVR is a low-dropout (LDO) voltage regulator from Texas Instruments, specifically designed to provide a fixed output voltage of 3.3V. This device comes in a 5-pin SOT-23 package. Here is a brief overview of its pin configuration and functions:
1. Pin 1 (IN): Input voltage pin. This is where the unregulated input voltage is supplied to the regulator.
2. Pin 2 (GND): Ground pin. This pin provides the ground reference for the LDO regulator.
3. Pin 3 (NR/FB): Noise reduction or feedback pin. For fixed-output versions like the TPS79133, this pin can be used to connect a capacitor to reduce noise.
4. Pin 4 (EN): Enable pin. This active-high pin turns the regulator on or off. Pulling it high enables the device, while pulling it low disables it.
5. Pin 5 (OUT): Output voltage pin. This is where the regulated 3.3V output is available to power the load.
This LDO regulator is well-suited for applications requiring a low noise and fast transient response, making it ideal for powering sensitive analog circuitry.
