NCV7361A
Advance Information
Voltage Regulator with
Integrated LIN Transceiver
The NCV7361A consists of a low drop voltage regulator,
5.0 V/50 mA and a LIN bus transceiver. The LIN transceiver is
suitable for LIN bus systems compatible to
“LIN−Protocol Specification” Rev. 1.3, 2.0 and SAE J2602.
The combination of voltage regulator and bus transceiver make it
ideal for a powerful and inexpensive cost effective slave node in a
LIN Bus system.

ELECTRICAL SPECIFICATIONS
All voltages are referenced to ground (GND). Positive
currents flow into the IC.
The maximum ratings (in accordance with IEC 134)
given in the table below are limiting values that do not lead
to a permanent damage of the device but exceeding any of

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values
(not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage
may occur and reliability may be affected.
