Note1:

Unless otherwise noted, these specifications apply: 0℃≦T_J≦70℃ for the WS317L;V_IN-V_OUT=5V and I_OUT= 40mA.

Although power dissipation is internally limited, these specifications are applicable for power dissipation up to

625mW. I_MAXis 100mA

Note2:

Note3:

Regulation is measure at constant junction temperature, using pulse testing with a low duty cycle. Changes in

output voltage due to heating effects are covered under the specification for thermal regulation.

Thermal resistance of the TO-92 package is 180℃/W junction to ambient with 0.4” leads from a PC board and 160

℃/W junction to ambient with 0.125” length to a PC board
