4. Low Quiescent Current: Features a very low quiescent current of approximately 60 µA, which helps in extending battery life in portable applications.
5. Dropout Voltage: Exhibits a low dropout voltage, typically around 230 mV at full load.
6. Regulation: Provides excellent line and load regulation.
7. Packages: Available in a compact SOT-23-5 package, which is ideal for space-constrained designs.
8. Thermal Protection: Includes thermal shutdown to protect against overheating.
9. Reverse Current Protection: Prevents reverse current flow, enhancing reliability.
These features make the TPS76033DBVR suitable for battery-powered devices, portable electronics, and other applications requiring efficient voltage regulation.
Pinout
1. Pin 1 (IN): This is the input pin where the unregulated DC voltage is applied. The input voltage should be higher than the desired output voltage for proper operation.
2. Pin 2 (GND): This is the ground pin and serves as the return path for the input and output currents.
3. Pin 3 (EN): The enable pin is used to turn the regulator on or off. Pulling this pin high enables the regulator, while pulling it low disables the output.
4. Pin 4 (OUT): This pin provides the regulated output voltage of 3.3V.
5. Pin 5 (NC or Bypass): This pin is typically not connected (NC) or used to connect a bypass capacitor to improve noise performance.
The TPS76033DBVR is ideal for battery-powered applications due to its low quiescent current and dropout voltage.
