Suggested Board Layout

This diagram illustrates a simple board layout for

use with the SRL10A-12 series. As recommended,

external components are placed as close to the

unit as possible. To help shield external circuitry,

the ground plane has been extended under the

unit. Any signal traces should not be routed

underneath the unit (unless they are on a layer

under the ground plane) to avoid unwanted noise

interference.

Output Voltage Trim

The output voltage level of the SRL10A-12 series is adjustable over

a wide range by the simple addition of an external resistor. This trim

resistor is connected between the circuit common and the trim input,

as shown in the diagram at left.

The required resistor value for various output levels is given in the

table above. To calculate the correct value for a different output

level, the formula is:
