LTC3388-1 Datasheet 20v High Efficiency Nanopower Step-down Regulator

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC®3388-1/LTC3388-3 are high efficiency step-down DC/DC converters with internal high side and synchronous power switches that draw only 720nA typical DC supply current at no load while maintaining output voltage regulation.

Capable of supplying 50mA of load current, the LTC3388-1/ LTC3388-3 also incorporate an accurate undervoltage lockout (UVLO)
