Exceeding the absolute maximum rating may damage the device.
The device is not guareented to function outside itsperating rating.
Devices are ESD sensitive. Handling precautions recommended.
The maximum allowable power dissipation at any T
allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. The
the SOT-23-6 mounted on a printed circuit board.
Output voltage temperature coeffiecient 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 50mA. Change in output voltage due to heating effects are covered by thermal regulation specification.
Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V
differential. For output voltages below 2.5V, dropout voltage is the input-to-output voltage differential with the minimum voltage being 2.5V.
Minimum input opertating voltage is 2.5V.
Ground pin current is the quiescent current per regulator 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 50mA load pulse at V
+ 1V; I
