NCP5661, NCV5661
Low Output Voltage,
Ultra-Fast 1.0 A Low Dropout
Linear Regulator with Enable
The NCP5661/NCV5661 is a high performance, low dropout linear
regulator designed for high power applications that require up to 1.0 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 NCP5661/NCV5661 also provides additional features
such as Enable and Error Flag (for the fixed output version),
increasing the utility of these devices. A thermally robust, 5 pin DPAK
or DFN 3x3.3 mm, 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 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
• NCV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q100
Qualified and PPAP Capable
• These are Pb−Free Devices
Applications
• Servers
• ASIC Power Supplies
• Post Regulation for Power Supplies
• Constant Current Source
• Networking Equipment
• Gaming and STB Modules
