LR432ATLT1G

LRC · Voltage Reference · SOT-23

LR432ATLT1G from LRC, in a SOT-23. 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	REF	input	Reference input of the adjustable regulator; the internal approximately 1.24 V reference is sensed here, with reference input current typically 0.15 µA and at most 0.4 µA.
2	CATHODE	passive	Cathode (K) of the regulator; continuous cathode current is rated 100 mA, cathode voltage 20 V absolute maximum, and the output adjusts from VREF up to 18 V with a minimum cathode current for regulation of 55 µA.
3	ANODE	passive	Anode (A) terminal of the regulator, the common terminal of the shunt path against which the cathode voltage and the cathode current limits are specified.
