LM4132DMF-3.3

Texas Instruments · Voltage Reference · SOT-23-5

LM4132DMF-3.3 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: drive EN between 65% of VIN and VIN to enable the device, or between 0 V and 35% of VIN to put it in shutdown (about 3 µA), and do not drive EN above VIN; it can be tied to VIN for always-on operation.
4 VIN power_in Input supply, which must be kept between VREF + 400 mV and 5.5 V (maximum input supply 5.5 V), with an input capacitor required between VIN and ground placed close to the device.
5 VREF power_out Precision voltage reference output (3.3 V for this variant), rated for up to 20 mA load current for the LM4132 device, with an output capacitor that is optional.
