APPLICATION NOTES
Maximize copper foil area connecting to all IC pins for optimum heat conduction. Place input and output bypass capacitors
close to the GND pin.
For best transient behavior and lowest output impedance, use as large a capacitor value as possible. The temperature
coefficient of the capacitance and Equivalent Series Resistance (ESR) should be taken into account. These parameters
can influence power supply noise and ripple rejection. In extreme cases, oscillation may occur. In order to maintain
stability, the output bypass capacitor value should be minimum 1
