NCV8502 Series
Micropower 150 mA LDO
Linear Regulators with
DELAY, Adjustable RESET,
and Monitor FLAG
The NCV8502 is a family of precision micropower voltage
regulators. Their output current capability is 150 mA. The family has
output voltage options for adjustable, 2.5 V, 3.3 V, 5.0 V, 8.0 V, and 10 V.
The output voltage is accurate within ±2.0% with a maximum
dropout voltage of 0.6 V at 150 mA. Low quiescent current is a feature
drawing only 90 mA with a 100 mA load. This part is ideal for any and
all battery operated microprocessor equipment.
Microprocessor control logic includes an active RESET (with
DELAY), and a FLAG monitor which can be used to provide an early
warning signal to the microprocessor of a potential impending RESET
signal. The use of the FLAG 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
external resistor divider to RADJ 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.
