Two low-cost capacitors and a diode are used in this circuit to provide up to 20 mA of output current. The LM2766 operates at 200-kHz switching frequency to reduce output resistance and voltage ripple. With an operating current of only 350 µA (operating efficiency greater than 90% with most loads) and 0.1-µA typical shutdown current, the LM2766 provides ideal performance for batterypowered systems. The device is manufactured in a SOT-23 6-pin package.
