LM4132CQ1MFR3.3

Texas Instruments · Voltage Reference · SOT-23-5

LM4132CQ1MFR3.3 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: an EN voltage between 65% of VIN and VIN enables the device, and 0 V to 35% of VIN disables it.
4 VIN power_in Input supply, which must be between VREF + 400 mV and 5.5 V.
5 VREF power_out Reference output, rated for a maximum load current of 25 mA for the LM4132-3.3-Q1 variant.
