Voltage Reference Shunt
Voltage Reference Shunt. Adjustable micropower shunt voltage reference. The output voltage may be set to any value between v ref (approximately 1.24v) and 18v with two external resistors.

For example, the cheapest variant of the lm431 requires an anode current of 1ma minimum. A shunt reference is functionally similar to a zener diode, where the voltage drop across the device is constant after the device reaches a minimum operating current. They feature low temperature drift, an initial accuracy of.
The Ts432Aix And Ts432Bix Has A
A shunt reference regulates the output voltage by adjusting its sink current to oppose changes in load current. They feature low temperature drift, an initial accuracy of. Our shunt voltage regulator portfolio includes 2.5v, 1.24v, and 0.6v reference voltage devices covering consumer, computing, industrial, and automotive applications.
The Output Voltage May Be Set To Any Value Between V Ref (Approximately 1.24V) And 18V With Two External Resistors.
Shunt references have these characteristics: A series reference is best when the load current may change often, while the input voltage is fairly constant and within the bounds of the device limits. As an alternate description, the shunt reference maintains a constant voltage at out by forcing the sum of load current and current through the reference to be constant.
The 2.5 V Reference Makes It Convenient To Obtain A Stable Reference From 5.0 V Logic Supplies, And Since The Tl431, A, B Operates As A Shunt Regulator, It Can Be Used As Either A Positive Or Negative.
Total \(p_{total(max)}\) total power dissipation (max) exact: Precision shunt voltage reference @ 125c. (for guidance in choosing between a series and a shunt voltage reference, see application note 4003, “series or.
The Shunt Reference Regulates The Load By Acting As A Constant Voltage Drop And Shunting Excess Current Not Required By The Load Through The Device To Ground.
The minimum operating current ranges from 60μa for Terminal voltage references, or adjustable voltage references. Reference power dissipation (max) exact:
The Serial Connections Of Ref5010 Basic Shunt Blocks Allow Exceptionally High Voltage References To Be Built (In Thousands Of Volts) With Very High Voltage Precision And Superb Temperature Stability.
Precision shunt voltage reference @ 27c. For example, the cheapest variant of the lm431 requires an anode current of 1ma minimum. A shunt reference is functionally similar to a zener diode, where the voltage drop across the device is constant after the device reaches a minimum operating current.
