Note 1:
“Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits.

= 40 mA. Although power dissi-
pation is internally limited, these specifications are applicable for power dissipations up to 625 mW. I
MAX
is 100 mA.
Note 3:
Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating effects are cov-
ered under the specification for thermal regulation.
Note 4:
Thermal resistance of the TO-92 package is 180C/W junction to ambient with 0.4" leads from a PC board and 160C/W junction to ambient with 0.125" lead
length to PC board. The M package
θ
JA
is 180C/W in still air.
