TS432ILT

STMicroelectronics · Voltage Reference · SOT-23

TS432ILT from STMicroelectronics, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 REF input Reference input. Sensed against the internal 1.24 V bandgap by the on-chip error amplifier; when V(REF) exceeds 1.24 V the internal shunt transistor sinks current between cathode and anode. Reference input current (Iref) is typically 50 nA (100 nA max at 25 °C, 200 nA max over temperature); absolute max reference input current is -0.05 to +3 mA. Program output with an external R1/R2 divider such that Vk = Vref·(1+R1/R2) + Iref·R1.
2 A passive Anode. Reference/return terminal of the shunt regulator, typically connected to circuit ground. All internal reference and cathode voltages are measured with respect to this pin.
3 K passive Cathode. Regulated shunt terminal; the device sinks cathode current to hold Vk at the programmed value (1.24 V to 10 V). Operating cathode voltage 1.24 V to 10 V, operating cathode current 60 µA to 12 mA (absolute max Vk = 12 V, Ik = -10 to +20 mA). Static impedance is typically 0.25 Ω (0.5 Ω max) over 100 µA to 12 mA.
