NCV4279

5.0 V Micropower 150 m A LDO Linear Regulator with DELAY, Adjustable RESET, and Sense Output

http://onsemi.com

The NCV4279 is a 5.0 V precision micropower voltage regulator with an output current capability of 150 m A.

MARKING

The output voltage is accurate within ±2.0% with a maximum

dropout voltage of 0.5 V at 100 m A. Low quiescent current is a feature drawing only 150 A with a 1.0 m A load. This part is ideal for any and

all battery operated microprocessor equipment.

D SUFFIX

Microprocessor control logic includes an active reset output RO CASE 751 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

AWLYWWG

The active Reset circuit operates correctly at an output voltage as CASE 751A1 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. = Assembly Location

The reset threshold voltage can be decreased by the connection of an WL, L = Wafer Lot external resistor divider to the RADJ lead. The regulator is protected YY, Y = Year WW, W = Work Week

against reverse battery, short circuit, and thermal overload conditions.
