9 Power Supply Recommendations
The input supply range must be at least 6 V, and needs a current-limiting resistor above 15 V. An input capacitor
of 4.7 µF (typical) is required as well. I_Q max is 3 mA, but additional current will be required to operate the
solenoid or relay.
10 Layout
10.1 Layout Guidelines
Routing for the SENSE pin should be careful to avoid noise sources. Routing for the output node and sense
node should be minimized. The trace for the solenoid or relay current should be wide in order to prevent any
unexpected voltage drop.
