NCV4279A

5.0 V Micropower 150 mA

LDO Linear Regulator with

DELAY, Adjustable RESET,

and Sense Output

http://onsemi.com

The NCV4279A is a 5.0 V precision micropower voltage regulator

with an output current capability of 150 mA.

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 150 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

external resistor divider to the R

lead. 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.

PIN CONNECTIONS

If the application requires pullup resistors at the logic outputs Reset

and Sense Out, the NCV4269A with integrated resistors can be used.
