LTC3541-1 Datasheet High Efficiency Buck + Vldo Regulator

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC3541-1 High Efficiency Buck + VLDO Regulator.

General Description

The LTC®3541-1 bines a synchronous buck DC/ DC converter with a very low dropout linear regulator (VLDO) to provide up to two output voltages from a single input voltage with minimal external ponents.

When configured for dual output operation, the LTC3541-1’s auto start-up
