HT385R-1.2 from HTCSEMI, in a SOP-8. 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 | Not internally connected; leave unconnected. |
| 2 | N.C. | unconnected | Not internally connected; leave unconnected. |
| 3 | N.C. | unconnected | Not internally connected; leave unconnected. |
| 4 | Anode | passive | Anode of the two-terminal bandgap voltage regulator diode; reverse current is limited to 30 mA maximum and forward current to 10 mA maximum (absolute maximum ratings, TA = 25°C). |
| 5 | N.C. | unconnected | Not internally connected; leave unconnected. |
| 6 | N.C. | unconnected | Not internally connected; leave unconnected. |
| 7 | N.C. | unconnected | Not internally connected; leave unconnected. |
| 8 | Cathode | passive | Cathode of the two-terminal bandgap reference; the regulated reverse breakdown voltage is 1.235 V for the HT385-1.2 version, operated between the minimum operating current (10 µA typ.) and 20 mA. |
