If the 8681L is an LDO, the pinout will typically be:
| Pin # | Name | Description | |-------|------|-------------| | 1 | VIN | Unregulated input voltage | | 2 | GND | Ground | | 3 | EN | Enable control (active high) | | 4 | NC | No connect (or bypass cap pin) | | 5 | VOUT | Regulated output voltage |
Note: Some 3-pin SOT-89 versions omit the EN pin and NC.
The 8681L is a mature, reliable, and predictable LNA for L-band applications. Its "magic" lies in the balance of 10 mA current and 27 dB gain. You won't find a 5V part with that gain-to-current ratio anywhere else.
Treat the datasheet with respect: Pay attention to the layout notes, over-engineer the power supply filtering, and use quality passives. Do that, and the 8681L will give you a noise floor low enough to hear satellites whispering from 20,000 km away.
