LM317 / LM337 +/-1.5V~37V Adjustable Dual Voltage Regulator Power Supply PCB

Description

Description:
The board is made of high-quality 1.6mm double-sided fiberglass board, double-sided routing, and gold immersion process.
PCB size: 7.5cm*7.5cm.
The two filter capacitor pins are installed with a "lead pin/hard pin" coexistence design. The diameter of the capacitor can be installed from 1.6cm-2.2cm, which can be extended to more filter capacitors. The layout adopts the classic one-point grounding, and the symmetrical layout of the components on both sides is beautiful and generous.
Input AC voltage requirements: 25V-0-25V
Output DC voltage range: ±1.5V to ±37V (the maximum cannot exceed 37V DC, exceeding the LM317/LM337V load will burn the component.)
