Minos · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89
HT7333 from Minos, in a SOT-89. 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 reference pin for the regulator (datasheet function: 地, ground). |
| 2 | VIN | power_in | Regulator input pin; the datasheet gives a maximum input voltage of 20 V for operation and an absolute maximum VIN of -0.3 V to +33 V, and recommends placing the input capacitor close to the VIN and VOUT pins. |
| 3 | VOUT | power_out | Regulated 3.3 V output pin (3.300 V typical, ±2%) that supplies up to 300 mA, and the datasheet recommends placing the output capacitor close to the VOUT pin. |
