Note3:
Unless otherwise noted, these specifications apply: 0℃≦TJ≦70℃ for the WS317L;VIN-VOUT=5V and IOUT= 40mA.
Although power dissipation is internally limited, these specifications are applicable for power dissipation up to
625mW. IMAX is 100mA
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
