LINEAR INTEGRATED CIRCUIT
4-CH DARLINGTON SINK
DRIVER AND 3-TERMINAL
0.2A 5V VOLTAGE
REGULATOR
DESCRIPTION
The UTC
MX2002D
is comprised of 4-ch Darlington Sink Driver
and 3-TERMINAL Voltage Regulator.
The Sink Driver is a high-voltage, high-current NPN darlington
driver. Every channel includes clamp diode for switching inductive
load. The applications of the UTC
MX2002D
include relay,
hammer, lamp and display (LED) drivers.
The 5V Voltage Regulator is a three-terminal regulator with
0.2A output current capability.
SOP-14
FEATURES
