LM4132BMFX-1.8

Texas Instruments · Voltage Reference · SOT-23-5

LM4132BMFX-1.8 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 it floating.
2 GND power_in Ground reference for the device.
3 EN input Enable input: drive it between 65% of VIN and VIN to enable the device, or between 0 V and 35% of VIN to put it in shutdown; VEN must not exceed VIN or the device does not operate correctly.
4 VIN power_in Input supply, which must satisfy VIN > VREF + 400 mV at ILOAD ≤ 10 mA and stay within the 5.5 V maximum input supply voltage; a CIN input capacitor is required close to this pin.
5 VREF power_out Precision reference output that sources up to 20 mA; an output capacitor is optional and must satisfy CIN ≥ COUT if used.
