TL432 Pinout and Package Details:
Package Type: The TL432AIDBZR comes in the SOT-23-3 package (a 3-pin small-outline transistor package). Pin Count: 3 pins in total. Pin Function Table for TL432AIDBZR: Pin Number Pin Name Pin Function Description Pin 1 Anode (A) The anode pin is connected to the input voltage in the shunt regulator configuration. This pin is where the voltage is applied, and the device operates to regulate the voltage across the cathode. Pin 2 Cathode (K) The cathode pin is connected to the output voltage of the regulator, providing a stable reference voltage when the device is in use. Pin 3 Ref (R) The reference pin (Ref) is used to control the regulation. The TL432 adjusts the voltage between the anode and the cathode to maintain the reference voltage on this pin. This pin can be used to set the output voltage in some applications by connecting external components (e.g., resistors).TL432 Detailed Pin Function:
Anode Pin (Pin 1):
Connected to the input voltage in the shunt regulator circuit.
This pin will experience the full input voltage, with the TL432 regulating the difference between the anode and cathode.
Cathode Pin (Pin 2):
Provides the regulated output voltage.
This pin is essential in maintaining voltage stability in the circuit.
Reference Pin (Pin 3):
Used for voltage regulation and feedback purposes.
The voltage here determines how the regulator operates and ensures accurate regulation of the voltage between the anode and cathode pins.
Circuit Principle:
The TL432 operates as a shunt regulator, where the reference voltage is provided via the Ref pin (Pin 3), and the device will adjust the voltage between the anode (Pin 1) and cathode (Pin 2) to keep the output voltage stable. The input voltage is applied to the anode, and the device will conduct current from the anode to the cathode to ensure that the voltage across the cathode matches the reference voltage. External resistors or other components can modify the output voltage and the feedback loop.
