9 Power Supply Recommendations

Power supply bypass capacitors are optional and may be required if the supply line is noisy. TI recommends that a local supply decoupling capacitor be used to reduce noise. For noisy environments, TI recommends a 100-nF supply decoupling capacitor placed closed across VDD and GND pins of LM57-Q1.
