| Pin No. | Symbol | Description | |---------|--------|-------------| | 1 | VIN | Input voltage (4.5V – 28V) | | 2 | GND | Common ground | | 3 | VOUT | Regulated output voltage | | 4 | ADJ | Output voltage adjustment (connect resistor divider to GND) |
Choose R2 = 1kΩ. Then R1 = (5V/0.8V – 1) * 1kΩ = 5.25kΩ (use 5.1kΩ + 150Ω in series). gyd-9e datasheet
A: No internal protection. Add an external Schottky diode in series with input if needed. | Pin No
The GYD-9E module contains internal inductors and capacitors. Do not apply reverse polarity or voltages above 30V, even momentarily. 4. Electrical Characteristics (Typical at 25°C, Vin=12V, Vout=5V) These values are representative of a healthy GYD-9E module: A: No internal protection
Mechanical dimensions: Typically 21.5mm (L) x 11.5mm (W) x 6.8mm (H), with 2.54mm pin spacing suitable for breadboards or perfboards. Exceeding these values may cause permanent damage:
