Low Voltage Adjustable Precision Shunt Regulator

PRODUCTION DATA SHEET

ABSOLUTE MAXI MUM RATI NGS ( 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.

3-Pin Plastic Package

(PC Mounted)

220°C/W

Thermal Resistance – Junction to Ambient, θJA

(Non-PC Mounted) 410°C/W

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.
