External Output Trimming

Output may optionally be trimmed (±10%) with external fixed resistors or an external trimpot as shown.

Output Noise

The output noise is measured with a 10uF tantalum capacitor and a 1.0uF ceramic capacitor across the output.

The VHB75 series allows the user to switch the module on and off electronically with the remote on/off feature. Logic control
