Low Output Voltage,
Ultra−Fast 2.0 A Low Dropout
Linear Regulator with Enable
The NCP5662/NCV5662 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/NCV5662 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
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
• 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 Site
and Control Changes
• These are Pb−Free Devices

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
