BU18TD2WNVX-TL

ROHM Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN-4-EP(1x1)

BU18TD2WNVX-TL from ROHM Semicon, in a DFN-4-EP(1x1). 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 VOUT power_out Regulated output voltage pin (1.0V to 3.4V versions, up to 200mA), needs a 0.47uF ceramic output capacitor (min 0.22uF) to GND.
2 GND power_in Ground pin; must be the minimum potential in the system.
3 STBY input ON/OFF control of output voltage: High (1.2V to 6.0V) is ON, Low (-0.3V to 0.3V) is OFF with output discharge active.
4 VIN power_in Power supply input, recommended operating range 1.7V to 6.0V, needs a 0.47uF ceramic input capacitor (min 0.22uF) to GND.
5 FIN passive Exposed substrate pad on the bottom (reverse FIN), connect to GND.
