The LM3480 is a very simple regulator, in the heritage of the classic LM317 type linear regulators. It uses an NPN pass device like the LM317, so it is also very easy to stabilize. Capacitor ESR does not affect this regulator”s stability, therefore, there are no ESR curves. MLCC (multi-layer ceramic) capacitors work well. We recommend the use of a 0.1uF capacitor as shown on the datasheet front page as a minimum capacitance.
