LTC1622 Datasheet PDF

Linear Technology LTC1622

the LTC1622 down when the input voltage falls below 2V. The LTC1622 boasts a ± 1.9% output voltage accuracy and consumes only 350µA of quiescent current. For applications where efficiency is a prime consideration and the load current varies from light to heavy, the LTC1622 can be configured for Burst ModeTM operation.
