TL4050B25IDBZR

Texas Instruments · Voltage Reference · SOT-23-3

TL4050B25IDBZR from Texas Instruments, in a SOT-23-3. 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 Cathode output Reference output cathode providing 2.5V ±5mV (IZ = 100μA, TA = 25°C) with temperature coefficient ±50ppm/°C (full range).
2 Anode power_in Supply input anode for shunt reference with operating cathode current from 60μA minimum (TA = 25°C) to 20mA (absolute maximum continuous).
3 NC unconnected Case pin with internal parasitic Schottky diode to pin 2; must be left floating or connected to pin 2 per section 8.2.
