NCV4279C
5.0 V Micropower 150 mA
LDO Linear Regulator with
DELAY, Adjustable RESET,
and Sense Output
www.onsemi.com
The NCV4279C is a 5.0 V precision micropower voltage regulator
with an output current capability of 150 mA.
MARKING
DIAGRAMS
The output voltage is accurate within 2.0% with a maximum
dropout voltage of 0.5 V at 100 mA. Low quiescent current is a feature
drawing only 125 mA with a 1.0 mA load. This part is ideal for any and
all battery operated microprocessor equipment.
Microprocessor control logic includes an active reset output RO
with delay and a SI/SO monitor which can be used to provide an early
warning signal to the microprocessor of a potential impending reset
signal. The use of the SI/SO monitor allows the microprocessor to
finish any signal processing before the reset shuts the microprocessor
down.

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
outside the regulation limits.

The reset threshold voltage can be decreased by the connection of an

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.
If the application requires pullup resistors at the logic outputs Reset
and Sense Out, the NCV4269C with integrated resistors can be used.

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.
An on−chip comparator is available to provide early
warning to the microprocessor of a possible reset signal. The
output is from an open collector driver. The reset signal
typically turns the microprocessor off instantaneously. This
can cause unpredictable results with the microprocessor.
The signal received from the SO pin will allow the
microprocessor time to complete its present task before
shutting down. This function is performed by a comparator
referenced to the band gap voltage. The actual trip point can

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
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
