Note 1. Unless otherwise noted, these specifications apply: –25
° ≤ TJ ≤ +125°C, VIN – VOUT = 5V,
IOUT = 40mA, and IMAX = 100mA. Although power dissipation is internally limited, these
specifications are applicable for power dissipations up to 625mW.
Note 2. Regulation is measured at constant junction temperature, using pulse testing with low duty
cycle. Changes in output voltage due to heating effects are covered under the specifications
for thermal regulation.
Note 3. Thermal resistance o the TO92 package is 180
°C/W junction to ambient with 0.4” leads from
a PC board and 160
°C/W junction to ambient with 0.125” lead length to PC board.
