HT7330-1-MS

MSKSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

HT7330-1-MS from MSKSEMI, in a SOT-23. 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 GND power_in Ground pin; the datasheet lists it only as the ground connection with no electrical limits stated for this pin.
2 VIN power_in Input pin with a maximum input voltage of 24 V, and input capacitors should be placed as close as possible to this pin.
3 VOUT power_out Regulated output pin for the 3.0 V output (HT7330-1-MS) rated for 300 mA, which needs an output capacitor greater than 2.2 μF to ground, tantalum recommended.

CAD (KiCad official)

  • Symbol: HT7330-1-MS
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ht7330-1-ms-etched.step / ht7330-1-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht7330-1-ms.step / ht7330-1-ms.glb are the bare package body.
