In Examples 2 and 3, the maximum output current is
calculated as 172mA and 476mA, respectively; howev-
er, the allowable output current cannot exceed 50mA.
Alternately, use Figures 6a and 6b to quickly determine
the maximum allowable output current for selected
ambient temperatures and input voltages.
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 minimum
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.
