Micropower 400 mA LDO
Linear Regulators with
DELAY, Adjustable RESET,
and General Use Comparator

MARKING
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.

ADJ
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.

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.
I
I
OUT
IN
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.

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
