CM431A
LOW VOLTAGE ADJUSTABLE SHUNT REGULATOR
ABSOLUTE MAXIMUM RATINGS
Cathode to Anode Voltage (VKA) (Note 2)
-0.3V to 18V
Continuous Cathode Current (IK)
-100mA to 150mA
Reference Input Current (IREF)
Maximum junction temperature range, TJ
Storage temperature range
Lead temperature (soldiering, 10 seconds)
-50uA to 10mA

Note :
1. For SOT-89 package, Thermal Resistance-Junction to Tab ( θJT ) = 35 OC/W. TJ = TTAB + (PD x θJT)
2. θJA: Thermal Resistance-Junction to Ambient
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.
