and a diode are used in this circuit to provide up to 20

mA of output current.

•

90% Typical Conversion Efficiency at 20 mA

•

0.1µA Typical Shutdown Current

The LM2765 operates at 50 kHz switching frequency

to reduce output resistance and voltage ripple. With

an operating current of only 130 µA (operating
