The TL430CLP is a shunt-type adjustable voltage reference from Texas Instruments, packaged in a through-hole TO-92-3 case. It provides a regulated output adjustable from a minimum of 2.75V up to 30V, with a cathode current of 2 mA and output current capability of 100 mA.
The ±9.09% tolerance is wide compared to precision references. For a shunt reference, this initial accuracy means the output voltage at a given set-point can vary significantly from unit to unit.
Output current and voltage range — sizing the shunt resistor
The 100 mA output current is relatively high for a shunt reference, allowing it to source or sink significant current through the programming resistor.
