ZHCSSL3R April 2000 – February 2025 LP2980-N
PRODUCTION DATA
Surface-mount multilayer ceramic capacitors are an attractive choice because of the relatively small physical size and excellent RF characteristics. However, these capacitors sometimes have ESR values lower than the minimum required by the LP2980-N (legacy chip), and relatively large capacitance change with temperature. Consult the manufacturer data sheet for the capacitor before selecting a value.
Test results of the LP2980-N (legacy chip) stability using multilayer ceramic capacitors show a minimum value of 2.2μF is typically needed for the 5V regulator. For lower output voltages, or better performance, use a higher value (such as 4.7μF).
Table 7-2 lists multilayer ceramic capacitors that are verified as appropriate for use with the LP2980-N.
