Note 2: Specifications in bold type are limited to -40oC

≤TJ≤125oC. Limits over temperature are guaranteed by design, but not

tested in production.

Note 3: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature

range.

Note 4: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load

regulation in the load range from 0.1mA to 500mA. Changes in output voltage due to heating effects are covered by the thermal

regulation specification.

Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 1% (TJ=25oC) or 2% (-

40oC

≤TJ≤125oC) below its nominal value measured at 1V differential.

Note 6: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the
