NCV4276C
400 mA Low-Drop Voltage
Regulator
The NCV4276C is a 400 mA output current integrated low dropout
regulator family designed for use in harsh automotive environments.
It includes wide operating temperature and input voltage ranges. The
device is offered with 3.3 V, 5.0 V, and adjustable voltage versions
available in 2% output voltage accuracy. It has a high peak input
voltage tolerance and reverse input voltage protection. It also
provides overcurrent protection, overtemperature protection and
inhibit for control of the state of the output voltage. The NCV4276C
family is available in DPAK and D2PAK surface mount packages.
The output is stable over a wide output capacitance and ESR range.
The NCV4276C has improved startup behavior during input voltage
transients.
The NCV4276C is pin for pin compatible with NCV4276B.

NCV4276C
Circuit Description
The NCV4276C is an integrated low dropout regulator
that provides a regulated voltage at 400 mA to the output.
It is enabled with an input to the inhibit pin. The regulator
voltage is provided by a PNP pass transistor controlled by
an error amplifier with a bandgap reference, which gives it
the lowest possible dropout voltage. The output current
capability is 400 mA, and the base drive quiescent current
is controlled to prevent oversaturation when the input
voltage is low or when the output is overloaded. The
regulator is protected by both current limit and thermal
shutdown. Thermal shutdown occurs above 150°C to
protect the IC during overloads and extreme ambient
temperatures.
Minimum ESR for CQ = 10 mF and 22 mF is native ESR
of ceramic capacitor with which the fixed output voltage
devices are performing stable. Murata ceramic capacitors
were used,
GCM32ER71E106KA57 (10 mF, 25V, X7R, 1210),
GRM32ER71E226ME15 (22 mF, 25V, X7R, 1210).
Calculating Bypass Capacitor
If usage of low ESR ceramic capacitors is demand in case
of Adjustable Regulator, connect the bypass capacitor Cb
between Voltage Adjust pin and Q pin according to
Applications circuit at Figure 4.
Parallel combination of bypass capacitor Cb with the
feedback resistor R1 contributes in the device transfer
function as an additional zero and affects the device loop
stability, therefore its value must be optimized. Attention
to the Output Capacitor value and its ESR must be paid. See
also Stability in High Speed Linear LDO Regulators
Application Note, AND8037/D for more information.
Optimal value of bypass capacitor is given by following
expression
Regulator
The error amplifier compares the reference voltage to a
sample of the output voltage (VQ) and drives the base of a
PNP series pass transistor via a buffer. The reference is a
bandgap design to give it a temperature−stable output.
Saturation control of the PNP is a function of the load
current and input voltage. Oversaturation of the output
power device is prevented, and quiescent current in the
ground pin is minimized. See Figure 4, Test Circuit, for
circuit element nomenclature illustration.

where
R1 = the upper feedback resistor
fz = the frequency of the zero added into the device
transfer function by R1 and Cb external components.
Set the R1 resistor according to output voltage
requirement. Chose the fz with regard on the output
capacitance CQ, refer to the table below.
Regulator Stability Considerations
The input capacitors (CI1 and CI2) are necessary to
stabilize the input impedance to avoid voltage line
influences. Using a resistor of approximately 1.0 W in
series with CI2 can stop potential oscillations caused by
stray inductance and capacitance.
The output 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.
The value for the output capacitor CQ, shown in Figure 3,
should work for most applications; see also Figures 5 to 8
for output stability at various load and Output Capacitor
ESR conditions. Stable region of ESR in Figures 5 to 8
shows ESR values at which the LDO output voltage does
not have any permanent oscillations at any dynamic
changes of output load current. Marginal ESR is the value
at which the output voltage waving is fully damped during
four periods after the load change and no oscillation is
further observable.
ESR characteristics were measured with ceramic
capacitors and additional series resistors to emulate ESR.
Low duty cycle pulse load current technique has been used
to maintain junction temperature close to ambient
temperature.

Inhibit Input
The inhibit pin is used to turn the regulator on or off. By
holding the pin down to a voltage less than 1.8 V, the output
of the regulator will be turned off. When the voltage on the
Inhibit pin is greater than 2.8 V, the output of the regulator
will be enabled to power its output to the regulated output
voltage. The inhibit pin may be connected directly to the
input pin to give constant enable to the output regulator.
Setting the Output Voltage (Adjustable Version)
The output voltage range of the adjustable version can be
set between 2.5 V and 20 V. This is accomplished with an
external resistor divider feeding back the voltage to the IC
back to the error amplifier by the voltage adjust pin VA.

In some cases, none of the packages will be sufficient to
dissipate the heat generated by the IC, and an external
heatsink will be required.
The internal reference voltage is set to a temperature stable
reference of 2.5 V.
The output voltage is calculated from the following
formula. Ignoring the bias current into the VA pin:
VI
Use R2 < 50 k to avoid significant voltage output errors
due to VA bias current.
Connecting VA directly to Q without R1 and R2 creates
an output voltage of 2.5 V.
Designers should consider the tolerance of R1 and R2
during the design phase.
The input voltage range for operation (pin 1) of the
adjustable version is between (VQ + 0.5 V) and 40 V.
Internal bias requirements dictate a minimum input voltage
of 4.5 V. The dropout voltage for output voltages less than
4.0 V is (4.5 V − VQ).

Figure 29. Single Output Regulator with Key
Performance Parameters Labeled
Heatsinks
A heatsink 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 RqJA:

is the maximum input voltage,
is the minimum output voltage,
is the maximum output current for the
application,
is the quiescent current the regulator
consumes at IQ(max).
RqJC appears in the package section of the data sheet.
Like RqJA, it too is a function of package type. RqCS and
RqSA are functions of the package type, heatsink and the
interface between them. These values appear in data sheets
of heatsink manufacturers.
Thermal, mounting, and heatsinking considerations are
discussed in the ON Semiconductor application note
AN1040/D.
Once the value of PD(max) is known, the maximum
permissible value of RqJA can be calculated:

The value of RqJA can then be compared with those in the
package section of the data sheet. Those packages with
RqJA less than the calculated value in Equation 2 will keep
the die temperature below 150°C.
