NCP58300
3.0A, Very Low-Dropout
(VLDO) Fast Transient
Response Regulator series
The NCP58300 series are high precision, very low dropout
(VLDO), low ground current positive voltage regulators that are
capable of providing an output current in excess of 3.0 A with a typical
dropout voltage lower than 370 mV at 3.0 A load current. The devices
are stable with tantalum output capacitors. This series consists initially
of an Adjustable output voltage version, with fixed voltage versions
planned in the future.

The NCP58300 series can withstand up to 18 V max input voltage.
Internal protection features consist of output current limiting, built−in
thermal shutdown and reverse output current protection. Logic level
enable and error flag pins are available on the 5−pin version.
The NCP58302 is an Adjustable voltage Device and is offered in
D2PAK−5 package.

APPLICATIONS INFORMATION
Output Capacitor and Stability

IN
OUT
The NCP58300 series requires an output capacitor for
stable operation. The NCP58300 series is designed to
operate with tantalum output capacitors. The recommended
output capacitance value is 10 mF or greater. Higher value
helps to improve transient response and noise reduction.
The value of output capacitor is dependent upon the output
current; lower currents allow smaller capacitors.
difference is less than 6.5 V in the application, the output
structure of these regulators is able to withstand output
voltage (backup battery as example) to be applied without
reverse current flow. Of course the additional current
flowing through the internal Feedback resistor divider at the
NCP58300 Fix voltage versions needs to be included in the
backup battery discharging calculations.
Input Capacitor
Adjustable Voltage Design
An input capacitor of 0.1 mF or greater is recommended
when the device is more than 4 inches away from the bulk
supply capacitance, or when the supply is a battery. Small,
surface−mount chip capacitors can be used for the
bypassing. The capacitor should be place within 1 inch of the
device for optimal performance. Larger values will help to
improve ripple rejection by bypassing the input of the
regulator, further improving the integrity of the output
voltage.
The NCP/NCV58302 Adjustable voltage Device Output
voltage is set by the ratio of two external resistors as shown
in Figure 18.The device maintains the voltage at the ADJ pin
at 1.24 V referenced to ground. The current in R2 is then
equal to1.24 V / R2, and the current in R1 is the current in
R2 plus the ADJ pin bias current. The ADJ pin bias current
flows from VOUT through R1 into the ADJ pin.

Overcurrent and Reverse Output Current Protection
The NCP58300 regulator is fully protected from damage
due to output current overload conditions. When NCP58300
output is overloaded, Output Current limiting is provided.
This limiting is linear; output current during overload
conditions is constant. The device is also capable to
withstand power−on or enable start−up with output shorted
to ground for the full Recommended Operating Conditions
range. These features are advantageous for powering
FPGAs and other ICs having current consumption higher
than nominal during their startup.
