LM4128AQ1MF1.8

Texas Instruments · Voltage Reference · SOT-23-5

LM4128AQ1MF1.8 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 floating.
2 GND power_in Ground reference pin for the device.
3 EN input Enable pin; the datasheet gives a maximum low input level of 35 %V and a minimum high input level of 65 %V, and with EN = 0 V the shutdown supply current is 3 µA typical (7 µA maximum).
4 VIN power_in Input supply, rated up to 5.5 V maximum, and must be at least VREF + 400 mV for regulation at 10 mA load.
5 VREF power_out Reference voltage output, with a maximum load current of 20 mA and stable with capacitive loads up to 10 µF.
