NCV8505/D
NCV8505 Series
Micropower 400 mA
LDO Linear Regulators
with ENABLE, DELAY,
and RESET
The NCV8505 is a family of precision micropower voltage
regulators. Their output current capability is 400 mA. The family has
output voltage options for Adjustable, 2.5 V, 3.3 V and 5.0 V.
The output voltage is accurate within ± 2.0% with a maximum
dropout voltage of 0.6 V at 400 mA. Low quiescent current is a feature
drawing less than 1.0 mA with ENABLE = 0 V. With ENABLE = 5.0 V,
the part only draws 200 mA with 100 mA load. This part is ideal for any
and all battery operated microprocessor equipment.
Microprocessor control logic includes an active RESET
(with
DELAY).
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 below
the regulation limits.
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.
