).
Copper pattern should be as large as possible. Power dissi-
pation is 600 mW for SOT-23L and 900 mV for SOT-89-5. A
low ESR capacitor is recommended. For low temperature
operation, select a capacitor with a low ESR at the lowest
operating temperature to prevent oscillation, degradation of
ripple rejection and increase in noise. The minimum recom-
mended capacitance is 2.2
