NCV8503/D

NCV8503 Series

Micropower 400 mA LDO

Linear Regulators

with ENABLE, DELAY,

Adjustable RESET, and

General Use Comparator

The NCV8503 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 reset threshold voltage can be decreased by the connection of

The general use comparator (FLAG/Monitor) is referenced to a

temperature stable voltage and provides 1.0 mA of drive current at its

open collector output.

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.
