NCV8504 Series
Micropower 400 mA LDO
Linear Regulators with
DELAY, Adjustable RESET,
and General Use Comparator
The NCV8504 is a family of precision micropower voltage
regulators. Their output current capability is 400 mA. The family has
output voltage options for Adjustable, 2.5 V, 3.3 V and 5.0 V.
The output voltage is accurate within ± 2.0% with a maximum
dropout voltage of 0.6 V at 400 mA. Low quiescent current is a feature
drawing only 100 μA with a 100 μA load. This part is ideal for any and
all battery operated microprocessor equipment.
Microprocessor control logic includes an active RESET (with
DELAY).
The active RESET circuit operates correctly at an output voltage as
low as 1.0 V. The RESET function is activated during the power up
sequence or during normal operation if the output voltage drops below
the regulation limits.
The reset threshold voltage can be decreased by the connection of
external resistor divider to RADJ lead.
The general use comparator (FLAG/Monitor) is referenced to a
temperature stable voltage and provides 1 mA of drive current at its
open collector output.
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. The
device has also been optimized for EMC conditions.

CIRCUIT DESCRIPTION
REGULATOR CONTROL FUNCTIONS
The NCV8504 contains the microprocessor compatible
control function RESET (Figure 13).
The DELAY lead provides source current (typically 4.0 μA)
to the external DELAY capacitor during the following
proceedings:
1. During Power Up (once the regulation threshold
has been verified).
2. After a reset event has occurred and the device is
back in regulation. The DELAY capacitor is
discharged when the regulation (RESET threshold)
has been violated. This is a latched incident. The
capacitor will fully discharge and wait for the
device to regulate before going through the delay
time event again.

A general use comparator is included whose positive input
terminal is tied to the on−chip bandgap voltage reference.
This provides a very temperature stable referenced
comparator with versatile use in any system. The trip point
can be programmed externally using a resistor divider to the
input monitor (MON) (Figure 15). The typical threshold is
1.29 V on the MON pin.
Figure 13. Reset and Delay Circuit Wave Forms
RESET Function
A RESET signal (low voltage) is generated as the IC
powers up until VOUT is within 1.5% of the regulated output
voltage, or when VOUT drops out of regulation,and is lower
than 4.0% below the regulated output voltage. Hysteresis is
included in the function to minimize oscillations.
The RESET output is an open collector NPN transistor,
controlled by a low voltage detection circuit. The circuit is
functionally independent of the rest of the IC thereby
guaranteeing that the RESET signal is valid for VOUT as low
as 1.0 V.
VMON
VBAT
The reset threshold can be made lower by connecting an
external resistor divider to the RADJ lead from the VOUT
lead, as displayed in Figure 14. This lead is grounded to
select the default value of 4.6 V (on the 5.0 V option).

of the circuit depicted in Figure 15. As the input voltage falls

CALCULATING POWER DISSIPATION IN A
SINGLE OUTPUT LINEAR REGULATOR
The maximum power dissipation for a single output
regulator (Figure 19) is:
FLAG
PD(max) + [VIN(max) * VOUT(min)] IOUT(max)
Figure 17. FLAG Monitor Circuit Waveform
where:
VIN(max) is the maximum input voltage,
VOUT(min) is the minimum output voltage,
IOUT(max) is the maximum output current for the
application, and
IQ is the quiescent current the regulator consumes at
IOUT(max).
Once the value of PD(max) is known, the maximum
permissible value of RqJA can be calculated:
SETTING THE DELAY TIME
The delay time is controlled by the Reset Delay Low
Voltage, Delay Switching Threshold, and the Delay Charge
Current. The delay follows the equation:
tDELAY +
[CDELAY(Vdt * Reset Delay Low Voltage)]
Delay Charge Current
Example:
Using CDELAY = 33 nF.
Assume reset Delay Low Voltage = 0.
Use the typical value for Vdt = 1.8 V (2.5 V, 3.3 V, and
5.0 V options).
Use the typical value for Delay Charge Current = 4.2 μA.
tDELAY +
(1)
) VIN(max)IQ
T
RqJA + 150°C * A
PD
(2)
The value of RqJA can then be compared with those in the
package section of the data sheet. Those packages with
RqJA’s less than the calculated value in equation 2 will keep
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
heatsink will be required.

STABILITY CONSIDERATIONS
The output or compensation capacitor helps determine
three main characteristics of a linear regulator: start−up
delay, load transient response and loop stability.
The capacitor value and type should be based on cost,
availability, size and temperature constraints. A tantalum or
aluminum electrolytic capacitor is best, since a film or
ceramic capacitor with almost zero ESR can cause
instability. 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
manufacturers data sheet usually provides this information.
The value for the output capacitor COUT shown in Figure 18
should work for most applications, however it is not
necessarily the optimized solution.

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 RqJA:

where:
RqJC = the junction−to−case thermal resistance,
RqCS = the case−to−heatsink thermal resistance, and
RqSA = the heatsink−to−ambient thermal resistance.
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 heat sink data sheets
of heat sink manufacturers.
