SC431L

The SC431L is a low voltage three terminal adjustable shunt regulator with thermal stability guaranteed over temperature. The output voltage can be adjusted to any value from 1.24V(VREF) to 20V with two external resistors. The SC431L has a typical dynamic output impedance of 0.2552. Active output circuitry provides a very sharp turn on characteristic,making the SC431 L an excellent replacement for zener diodes.

Features of the SC431L are:(1)low voltage operation (1.24V); (2)adjustable output voltage Vo=Vref to 20V; (3)wide operating current range 60A to 100mA; (4)low dynamic output impedance 0.25 typ; (5)trimmed bandgap design±0.5%; (6)upgrade for TLV431A.In no event shall Sensitron Semiconductor be liable for any damages that may result from an accident or any other cause during operation of the user's units according to the datasheet(s). Sensitron Semiconductor assumes no responsibility for any intellectual property claims or any other problems that may result from applications of information, products or circuits described in the datasheets.

The absolute maximum ratings of the SC431L can be summarized as:(1)cathode voltage:20V;(2)lead temperature:260;(3)continous cathode current:100mA;(4)operating junction temperature range:-40 to 150;(5)storage temperature range:-65 to 150.The products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
