TP431N124S5

TECH PUBLIC · Voltage Reference · SOT-23-5

TP431N124S5 from TECH PUBLIC, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected Not connected internally, but attached to the substrate and must be connected to ANODE or left open.
2 NC unconnected Not connected internally, but attached to the substrate and must be connected to ANODE or left open.
3 CATHODE passive Cathode of the shunt regulator, with maximum cathode voltage 18 V and continuous cathode current range of -100 to +150 mA.
4 REF input Reference input that sets the output voltage via an external resistor divider, with Vref of 1.24 V typical and a maximum reference input current of 10 mA.
5 ANODE power_in Anode of the regulator, the ground reference to which all voltage ratings are specified.
