Please also see the recommended pattern layout for your reference. Should it not be possible to place the input capacitor nearby, the regulated output level may increase up to the VDD level while the load of the DC/DC converter increases and the regulator output is at almost no load. ■ ELECTRICAL CHARACTERISTICS (Continued) |
