When incorporating the Highway 09 into your next design, pay special attention to input/output capacitor selection, thermal management, and PCB layout. Always refer to the manufacturer-provided datasheet for the exact revision you are using, as minor electrical variations can exist between production batches.
| Pin Number | Pin Name | Description | |------------|----------|-------------| | 1 | VIN (Input) | Unregulated input voltage. Bypass with a 10µF capacitor to ground. | | 2 | GND (Ground) | Common ground for input and output circuits. | | 3 | VOUT (Output) | Regulated output. Requires a 10µF to 22µF output capacitor for stability. | | 4 (SOP-8 only) | ADJ/EN | Adjust (for variable version) or Enable (shutdown when low). | highway 09 ic datasheet
For the SOP-8 version, pins 5-8 are typically connected to a heatsink pad or left NC. Always verify with the specific manufacturer’s datasheet. 3. Absolute Maximum Ratings Exceeding any of the following ratings will likely destroy the IC. This table is based on typical Highway 09 specifications. When incorporating the Highway 09 into your next
