NCV8501 Series
Micropower 150 m A LDO Linear Regulators with ENABLE, DELAY, RESET, and Monitor Flag
http://onsemi.com
The NCV8501 is a family of precision micropower voltage regulators. Their output current capability is 150 m A. The family has
output voltage options for adjustable, 2.5 V, 3.3 V, 5.0 V, 8.0 V, and 10 V.
D SUFFIX
The output voltage is accurate within ± 2.0% with a maximum
CASE 7511
dropout voltage of 0.6 V at 150 m A. Low quiescent current is a feature drawing only 90 µA with a 100 µA load. This part is ideal for any and all battery operated microprocessor equipment.
SOIC 16 LEAD
Microprocessor control logic includes an active RESET (with
WIDE BODY
DELAY), and a flag monitor which can be used to provide an early
EXPOSED PAD
warning signal to the microprocessor of a potential impending RESET PDW SUFFIX
signal. The use of the flag monitor allows the microprocessor to finish CASE 751R
any signal processing before the RESET shuts the microprocessor down.
The active RESET circuit operates correctly at an output voltage as MARKING DIAGRAMS low as 1.0 V. The RESET function is activated during the power up SO–8 SOW–16
sequence or during normal operation if the output voltage drops E PAD
outside the regulation limits.
The regulator is protected against reverse battery, short circuit, and ALYW
thermal overload conditions. The device can withstand load dump NCV8501x
transients making it suitable for use in automotive environments. The
AWLYYWW
device has also been optimized for EMC conditions.
