LTC3446 Datasheet - Linear Technology

LTC3446 Monolithic Buck Regulator

The LTC®3446 combines a synchronous buck DC/DC converter with two very low dropout (VLDO) linear regulators to provide up to three stepped-down output voltages from a single input voltage. The input voltage range is ideally suited for Li-Ion battery-powered applications, as well as powering low volt.
