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. |
