LM4132EMFX-4.1

Texas Instruments · Voltage Reference · SOT-23-5

LM4132EMFX-4.1 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; leave floating.
2 GND power_in Ground reference for the device.
3 EN input Enable pin: drive between 65% of VIN and VIN to enable, or 0 V to 35% of VIN to shut down (about 3 µA shutdown current); it has an internal pullup of about 2 µA and must not be driven above VIN.
4 VIN power_in Input supply, which must be at least VREF + 400 mV (for ILOAD ≤ 10 mA) and no more than 5.5 V.
5 VREF power_out Reference voltage output, which can source up to 20 mA for the LM4132 and does not require an output capacitor or buffer amplifier.
