VRD1818LTX from AnaSem, in a SOT-23-6. 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 | EN1 | input | Channel 1 enable input; high level 1.2V to 6.0V enables, low level max 0.3V shuts down channel 1 and auto-discharges VOUT1 via about 160 ohm. |
| 2 | VIN | power_in | Voltage input shared by both channels, operating range 1.6V to 6.0V (absolute max 7.0V), with a recommended 1.0uF input capacitor to VSS. |
| 3 | EN2 | input | Channel 2 enable input; high level 1.2V to 6.0V enables, low level max 0.3V shuts down channel 2 and auto-discharges VOUT2 via about 160 ohm. |
| 4 | VOUT2 | power_out | Channel 2 regulated output, up to 250mA with at least 1.0uF ceramic capacitor to VSS and not to exceed VIN+0.3V. |
| 5 | VSS | power_in | Power ground. |
| 6 | VOUT1 | power_out | Channel 1 regulated output, up to 250mA with at least 1.0uF ceramic capacitor to VSS and not to exceed VIN+0.3V. |
