TYPICAL APPLICATION CIRCUIT

(1) ON/OFF pins must be pulled high through a 10kΩ pull-up resistor.

(2) Generally a series regulator may cause oscillation, depending on the selection of external parts. The following

conditions are recommended for this IC. However, be sure to perform sufficient evaluation under the actual

usage conditions for selection, including evaluation of temperature characteristics.

2.2μF or more
