LM4132CMFX-4.1

Texas Instruments · Voltage Reference · SOT-23-5

LM4132CMFX-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 that should be left floating.
2 GND power_in Ground reference pin; the input capacitor CIN must be placed close to VIN and GND.
3 EN input Enable input: the device is enabled when VEN is between 65% of VIN and VIN, disabled (shutdown) when VEN is between 0 V and 35% of VIN, has an internal pullup of about 2 µA, and does not operate correctly if VEN is greater than VIN.
4 VIN power_in Input supply that must stay above VREF + 400 mV (at ILOAD ≤ 10 mA) and no higher than the 5.5 V maximum input supply voltage, with an input capacitor CIN required close to the pin.
5 VREF power_out Precision reference output that can source up to 20 mA and does not require an output capacitor or buffer amplifier.
