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)

Error Flag
An Error Flag is triggered when the output voltage is out of regulation excluding transient signals
(Fixed Version) that may occur. Requires a pullup resistor f 100 kW.

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.
NOTE: This device series contains ESD protection and exceeds the following tests:
Human Body Model (HBM) JESD 22−A114−B
Machine Model (MM) JESD 22−A115−A.
The maximum package power dissipation is:
TJ(max) * TA
PD +
RqJA
The bipolar process employed for this IC is fully characterized and rated for reliable 18 V VCCmax operation. To avoid damaging
the part or degrading it’s reliability, power dissipation transients should be limited to under 30 W for D2PAK.
For open−circuit to short−circuit transient,
PDTransient = VCCmax * ISC.
