ZHCSMO2A June 2022 – November 2022 LMR51430
PRODUCTION DATA
The LMR51430 device requires a high frequency input decoupling capacitor or capacitor. The typical recommended value for the high frequency decoupling capacitor is 4.7 μF or higher. TI recommends a high-quality ceramic type X5R or X7R with a sufficient 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, two 4.7-μF, X7R dielectric capacitor rated for 50 V are used for the input decoupling capacitor. The equivalent series resistance (ESR) is approximately 10 m? and the current rating is 1 A. Include a capacitor with a value of 0.1 μF for high-frequency filtering and place it as close as possible to the device pins.
