Alternately, use Figures 5a and 5b to quickly determine the maximum allowable output current for selected ambient temperatures and input voltages. Output-Capacitor Selection and Regulator Stability For stable operation over the full temperature range and with load currents up to 50mA, use a low-ESR 2.2µF (min) ceramic or tantalum output capacitor. Use larger output-capacitor values such as 22µF to reduce noise, improve load-transient response, and power- supply rejection. Some ceramic dielectrics exhibit large capacitance and ESR variations with temperature. Ensure the mini- mum capacitance under worst-case conditions does not drop below 1.3µF to ensure output stability. With an X7R dielectric, 2.2µF should be sufficient at all operat- ing temperatures.
