LTC3541-3 Datasheet (Linear Technology) - High Efficiency Buck + VLDO Regulator

LTC3541-3, High Efficiency Buck + VLDO Regulator

The LTC®3541-3 combines a synchronous buck DC/DC converter with a very low dropout linear regulator (VLDO™ regulator) and internal feedback resistor networks to provide two output voltages from a single input voltage with minimum external components.

When configured for dual output operation, the LT
