NCP5662 Datasheet, PDF (1/12 Pages) ON Semiconductor – Low Output Voltage, Ultra-Fast 2.0 A Low Dropout Linear Regulator with Enable

NCP5662
Low Output Voltage,
Ultra−Fast 2.0 A Low Dropout
Linear Regulator with Enable
The NCP5662 is a high performance, low dropout linear regulator
designed for high power applications that require up to 2.0 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 NCP5662 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 (26 mV_rms)
• 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
