HT385R-1.2

HTCSEMI · Voltage Reference · SOP-8

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.
