S-812C33AUA-C2NT2G

ABLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

S-812C33AUA-C2NT2G from ABLIC, in a SOT-89-3. 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 VSS power_in GND pin, the reference for the input, output and ON/OFF voltage ratings (VIN absolute maximum is VSS - 0.3 V to VSS + 18 V).
2 VIN power_in Input voltage pin; the IC is rated for an input of 16 V max. and the absolute maximum input is VSS - 0.3 V to VSS + 18 V.
3 VOUT power_out Regulated output voltage pin; the absolute maximum output voltage is VSS - 0.3 V to VIN + 0.3 V.
