LM4132BQ1MFR2.5

Texas Instruments · Voltage Reference · SOT-23-5

LM4132BQ1MFR2.5 from Texas Instruments, 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 N/C unconnected No-connect pin that should be left floating on the PCB.
2 GND power_in Ground reference pin for the device.
3 EN input Enable input: drive EN between 65% of VIN and VIN to enable the reference, or between 0 V and 35% of VIN to disable it, and never let EN exceed VIN; an internal pullup of about 2 µA lets it float or be tied to VIN.
4 VIN power_in Input supply that must stay between VREF + 400 mV and 5.5 V at a 10 mA load, with the absolute maximum on any input being 6 V.
5 VREF power_out Reference voltage output that sources up to 20 mA for the LM4132, and is current-limited to 75 mA with indefinite protection when shorted to ground.
