Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
The maximum allowable power dissipation at any T
allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. The
(M5) is 235 C/W and the TO-92 (Z) is 180 C/W (0.4" leads) or 160 C/W (0.25" leads) soldered to a PC board. See “Thermal Considerations.”
Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
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 180mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification.
Dropout voltage is the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differential.
Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the sum of
the load current plus the ground pin current.
Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied, excluding load or line
regulation effects. Specifications are for a 180mA load pulse at V
+125 C for 1.8V version; unless noted.
