11 Power Supply Recommendations

The LMC567 is designed to operate with an input power supply range between 2 V and 9 V. Therefore, the output voltage range of power supply must be within this range and well regulated. The current capability of upper power must not exceed the maximum current limit of the power switch. Because the operating frequency of the device could be very high for some applications, the decoupling of power supply becomes critical, so is required to place a proper decoupling capacitor as close as possible to VCC pin. Low equivalent-series-resistance (ESR) ceramic capacitor, typically 0.1 µF, is typically used. This capacitor must be placed within 2 mm of the supply pin.
