NCP5667
3.0 A, Low Dropout Linear
Regulator with Enhanced ESD
Protection
The NCP5667 is a high performance, low dropout linear regulator
designed for high power applications that require up to 3.0 A current.
A thermally robust, 3 pin D2PAK, combined with an architecture that
offers low ground current (independent of load), provides for a
superior high-current LDO solution.
Features
•ă±1% Output Voltage Accuracy
•ăUltra-Fast Transient Response (Settling Time: 1-3 ms)
•ăEnhanced ESD Ratings: 4 kV (HBM), 400 V (MM)
•ăLow Ground Current Independent of Load (3.0 mA Maximum)
•ăCurrent Limit Protection
•ăThermal Protection
•ăPower Supply Rejection Ratio > 65 dB
•ăStable with Aluminum, Tantalum and Ceramic Capacitors
•ăFunctional Substitute for LM323
•ăThis is a Pb-Free Device
Applications
•ăServers
•ăDTV and Flat Panel Applications
•ăPost Regulation for Power Supplies
•ăLaptop Computing Applications
•ăUSB Powered Applications
•ăNetworking Equipment
•ăGaming and STB Modules
