NCP5663

Low Output Voltage,

Ultra−Fast 3.0 A Low Dropout

Linear Regulator with Enable

The NCP5663 is a high performance, low dropout linear regulator

designed for high power applications that require up to 3.0 A current.

It is offered in both fixed and adjustable output versions. With output

voltages as low as 0.9 V and ultra−fast response times for load

transients, the NCP5663 also provides additional features such as

Enable and Error Flag (for the fixed output version), increasing the

utility of this device. A thermally robust, 5 pin D2Pak, combined with

an architecture that offers low ground current (independent of load),

provides for a superior high−current LDO solution.

Features

• Ultra−Fast Transient Response (Settling Time: 1−3 ms)

• Low Noise Without Bypass Capacitor (28 mVrms)

• Low Ground Current Independent of Load (3.0 mA Maximum)

• Fixed/Adjustable Output Voltage Versions

• Enable Function

• Error Flag (Fixed Output Version)

• Current Limit Protection

• Thermal Protection

• 0.9 V Reference Voltage for Ultra−Low Output Operation

• Power Supply Rejection Ratio > 65 dB

• This is a Pb−Free Device

Applications

• Servers

• ASIC Power Supplies

• Post Regulation for Power Supplies

• Constant Current Source

• Networking Equipment

• Gaming and STB Modules
