12.1 Layout Guidelines

Make sure that the connection to the V_DD pin is low impedance. Good analog design practice recommends placing a minimum 0.1-µF ceramic capacitor as near as possible to the V_DD pin to GND. If using the TPS3838 variant, be sure to follow the Recommended Operating Conditions to determine the pullup resistor value. Larger transients and faster slew rates on V_DD should use larger input capacitors. If not using MR, tie to V_DD to reduce current consumption.
