NCV4274C  
400 mA Low Dropout  
Voltage Regulator  
Description  
The NCV4274C is a precision micro−power voltage regulator with  
an output current capability of 400 mA available in the DPAK and  
D2PAK packages.  
www.onsemi.com  
The output voltage is accurate within 2.0% with a maximum  
dropout voltage of 0.5 V with an input up to 40 V. Low quiescent  
current is a feature drawing only 125 mA with a 1 mA load. This part is  
ideal for automotive and all battery operated microprocessor  
equipment.  
The regulator is protected against reverse battery, short circuit, and  
thermal overload conditions. The device can withstand load dump  
transients making it suitable for use in automotive environments.

APPLICATION DESCRIPTION  
Output Regulator  
Once the value of P  
is known, the maximum  
D(max)  
The output is controlled by a precision trimmed reference  
and error amplifier. The PNP output has saturation control  
for regulation while the input voltage is low, preventing over  
saturation. Current limit and voltage monitors complement  
the regulator design to give safe operating signals to the  
processor and control circuits.  
permissible value of R  
can be calculated:  
qJA  
ǒ
Ǔ
150 C * TA  
(eq. 2)  
PqJA  
+
PD  
The value of R  
can then be compared with those in the  
qJA  
package section of the data sheet. Those packages with  
’s less than the calculated value in Equation 2 will keep  
R
qJA  
Stability Considerations  
the die temperature below 150°C. In some cases, none of the  
packages will be sufficient to dissipate the heat generated by  
the IC, and an external heat sink will be required. The current  
flow and voltages are shown in the Measurement Circuit  
Diagram.  
The input capacitor C in Figure 2 is necessary for  
I1  
compensating input line reactance. Possible oscillations  
caused by input inductance and input capacitance can be  
damped by using a resistor of approximately 1 W in series  
with C  
I2.  
The output or compensation capacitor helps determine  
three main characteristics of a linear regulator: startup delay,  
load transient response and loop stability.  
The capacitor value and type should be based on cost,  
availability, size and temperature constraints. The  
aluminum electrolytic capacitor is the least expensive  
solution, but, if the circuit operates at low temperatures  
(−25°C to −40°C), both the value and ESR of the capacitor  
will vary considerably. The capacitor manufacturer’s data  
sheet usually provides this information.  
Heat Sinks  
A heat sink effectively increases the surface area of the  
package to improve the flow of heat away from the IC and  
into the surrounding air.  
Each material in the heat flow path between the IC and the  
outside environment will have a thermal resistance. Like  
series electrical resistances, these resistances are summed to  
determine the value of R  
:

(eq. 3)  
Where:  
The value for the output capacitor C shown in Figure 2  
Q
R
R
R
= the junction−to−case thermal resistance,  
should work for most applications; however, it is not  
necessarily the optimized solution. Actual Stability Regions  
are shown in a graphs in the Typical Performance  
Characteristics section.

= the case−to−heat sink thermal resistance, and  
= the heat sink−to−ambient thermal resistance.

Calculating Power Dissipation in a Single Output  
Linear Regulator  
The maximum power dissipation for a single output  
regulator (Figure 3) is:  
functions of the package type, heat sink and the interface  
between them. These values appear in data sheets of heat  
sink manufacturers.  
Thermal, mounting, and heat sinking are discussed in the  
ON Semiconductor application note AN1040/D, available  
on the ON Semiconductor Website.
