4-CH DARLINGTON SINK
DRIVER AND 3-TERMINAL
0.2A 5V VOLTAGE
REGULATOR
DESCRIPTION
SOP-14
LINEAR INTEGRATED CIRCUIT
The UTC
ULN202L05
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
ULN202L05
include relay,
hammer, lamp and display (LED) drivers.
The 5V Voltage Regulator is a three-terminal regulator with
0.2A output current capability.
FEATURES
For Darlington Sink Drivers
* Output current (single output): 500mA max
* High sustaining voltage output: 50V min
* Output clamp diodes
* Inputs compatible with various types of logic
For 5V VOLTAGE REGULATOR
* Output Current up to 200mA
* Thermal Overload Shutdown Protection
* Short Circuit Current Limiting

Notes: 1. The Maximum steady state usable output current are dependent on input voltage, heat sinking, lead length
of the package and copper pattern of PCB. The data above represent pulse test conditions with junction
temperatures specified at the initiation of test.
2. Power dissipation<0.5W.
