PRODUCTION DATA
The LMR51603 device requires a high frequency input decoupling capacitor or capacitor. The typical recommended value for the high frequency decoupling capacitor is 1µF or higher. TI recommends a high-quality ceramic type X5R or X7R with sufficiency voltage rating. The voltage rating must be greater than the maximum input voltage. To compensate the derating of ceramic capacitors, TI recommends a voltage rating of twice the maximum input voltage. For this design, one 1µF , X7R dielectric capacitor rated for 100V is used for the input decoupling capacitor. The equivalent series resistance (ESR) is approximately 10mΩ, and the current rating is 100mA. Include a capacitor with a value of 0.1µF for high-frequency filtering and place the capacitor as close as possible to the device pins.
