POWER_BUFFER_BOOSTS_REFERENCE_CURRENT

Published:2009/7/16 21:24:00 Author:Jessie | From:SeekIC

A method of boosting the output current of a reference and also protecting against overloads is shown in Fig. 66-5. IC1 acts as a power buffer. The LT1027 forces the output of VOUT and ground to be 5 V. The RC damper (50Ω and 0.1 μF) provides loop stability. The output might oscillate if low ESR capacitors are connected to it, so use aluminum electrolytic or tantalum capacitors instead of ceramic or mylar.
