TLV431AIDBZR Pinout and Functions
Package Type: The TLV431AIDBZR comes in a SOT-23-5 package (5-pin package). Pinout Details:Here is the pinout for the TLV431AIDBZR package (SOT-23-5):
Pin Number Pin Name Description 1 Anode (A) Input pin for the reference voltage. This is where you provide a voltage reference for the device. 2 Cathode (K) Output pin that provides the regulated reference voltage. 3 Ref (R) Reference input. This pin is used to set the reference voltage for the regulation. 4 N.C. (Not Connected) This pin is not internally connected to any part of the IC, it is unused in this package. 5 Ground (GND) Ground pin for the IC.Circuit Principle Overview:
The TLV431AIDBZR is a shunt voltage reference. It operates as a low dropout voltage regulator, providing a stable output voltage that is set by an external resistor network. This voltage reference is commonly used in applications requiring precise voltage regulation, such as in analog-to-digital converters (ADC) or voltage regulators.
It essentially works by maintaining the voltage difference between the anode and cathode to be a fixed value, determined by the internal reference. When the input voltage exceeds this reference value, the device starts conducting to clamp the voltage and provide a regulated output.
