Low Voltage Adjustable Precision Shunt Regulator
PRODUCTION DATA SHEET
ABSOLUTE MAXIMUM RATINGS (NOTE 1)
Cathode to Anode Voltage (VKA)..................................................................-0.3V to +20V
Reference Input Current (IREF) .....................................................................-50µA to 10µA
Continuous Cathode Current (IK)............................................................... -25mA to 25mA
Operating Junction Temperature................................................................................ 150°C
Storage Temperature....................................................................................-65ºC to 150°C
RoHS / Pb-free Peak Package Solder Reflow Temperature
(40 second maximum exposure) ....................................................................260°C (+0,-5)
Note 1: Exceeding these ratings could cause damage to the device. All voltages are with respect to
Ground. Currents are positive into, negative out of specified terminal.
THERMAL DATA
SC 3-Pin Plastic Package
Thermal Resistance – Junction to Ambient, θJA
(PC Mounted)
(Non-PC Mounted)
220°C/W
410°C/W
LP 3-Pin Plastic Package
Thermal Resistance – Junction to Ambient, θJA
156°C/W
Junction Temperature Calculation: TJ = TA + (PD x θJA).
The θJA numbers are guidelines for the thermal performance of the device/pc-board
system. All of the above assume no ambient airflow.
