ON NCP5663DS18R4G Low output voltage, ultra-fast 3.0 a low dropout linear regulator with enable Datasheet

NCP5663, NCV5663
Low Output Voltage,
Ultra-Fast 3.0 A Low Dropout
Linear Regulator with Enable
The NCP5663/NCV5663 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/NCV5663 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.

APPLICATION INFORMATION
The NCP5663/NCV5663 is a high performance low
dropout 3.0 A linear regulator suitable for high power
applications, featuring an ultra−fast response time and low
noise without a bypass capacitor. It is offered in both fixed
and adjustable output versions with voltages as low as 0.9 V.
Additional features, such as Enable and Error Flag (fixed
output version) increase the utility of the
NCP5663/NCV5663. It is thermally robust and includes the
safety features necessary during a fault condition, which
provide for an attractive high current LDO solution for
server, ASIC power supplies, networking equipment
applications, and many others.

Current Limit Operation
As the peak output current increases beyond its limitation,
the device is internally clampled to 4.5 A, thus causing the
output voltage to decrease and go out of regulation. This
allows the device never to exceed the maximum power
dissipation.
Input Capacitor
The recommended input capacitor value is a 150 mF
OSCON with an Equivalent Series Resistance (ESR) of
50 mW. It is especially required if the power source is
located more than a few inches from the
NCP5663/NCV5663. This capacitor will reduce device
sensitivity and enhance the output transient response time.
The PCB layout is very important and in order to obtain the
optimal solution, the Vin and GND traces should be
sufficiently wide to minimize noise and unstable operation.
Error Flag Operation
The Error Flag pin on the NCP5663/NCV5663 will
produce a logic Low when it drops below the nominal output
voltage. Refer to the electrical characteristics for the
threshold values at which point the Error Flag goes Low.
When the NCP5663/NCV5663 is above the nominal output
voltage, the Error Flag will remain at logic High.
The external pullup resistor needs to be connected
between Vin and the Error Flag pin. A resistor of
approximately 100 kW is recommended to minimize the
current consumption. No pullup resistor is required if the
Error Flag output is not being used.
Output Capacitor
Proper output capacitor selection is required to maintain
stability. The NCP5663/NCV5663 is stable for Cout as low
as 10 mF (Figures 15 and 16) and guaranteed to be stable at
an output capacitance of, Cout > 33 mF with an ESR between
50 mW and 300 mW over the output current range of 10 mA
to 3.0 A. For PCB layout considerations, place the
recommended ceramic capacitor close to the output pin and
keep the leads short. This should help ensure ultra−fast
transient response times.
Thermal Consideration
This series contains an internal thermal limiting circuit
that is designed to protect the regulator in the event that the
maximum junction temperature is exceeded. This feature
provides protection from a catastrophic device failure due to
accidental overheating. It is not intended to be used as a
substitute for proper heat sinking. The maximum device
power dissipation can be calculated by:
Adjustable Output Operation
The application circuit for the adjustable output version is
shown in Figure 1. The reference voltage is 0.9 V and the
adjustable pin current is typically 40 nA. A resistor divider
network, R1 and R2, is calculated using the following
formula:

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.
