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.

Output Voltage Temperature Coefficient is defined as worst case voltage change divided by the total temperature range. Guaranteed by
design.
10. Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or
line regulation effects. Specifications are for a 4 W pulse for T = 10 ms.
11. Comparator thresholds are expressed in terms of a voltage differential at the Adjust terminal below the nominal reference voltage measured
at 6V input. To express these thresholds in terms of output voltage change, multiply by the error amplifier
gain = V
OUT
/V
REF
= (R1 + R2)/R2.
For example, at a programmed output voltage of 5 V, the Error output is guaranteed to go low when the output drops by
95 mV x 5 V/1.240 V = 384 mV. Thresholds remain constant as a percent of V
OUT
as V

is varied, with the dropout warning occurring at
typically 5% below nominal, 7.7% guaranteed.
