NCV4269C
5.0 V Micropower 150 mA
LDO Linear Regulator with
DELAY, Adjustable RESET,
and Sense Output
The NCV4269C 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 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
external resistor divider to the R_ADJ 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.
