NOTES:
Note 1: Maximum positive supply voltage of 20V must be of limited duration (<100ms) and duty cycle of less than 1%. The
maximum continuous supply voltage is 16V.
Note 2: Full load current (I
Note 3: V
temperature rise.
Note 4 Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load current
plus the ground pin current.
Note 5: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Note 6: Thermal regulation is defined as the change in output voltage at time T after a change in power dissipation is applied,
excluding load / line regulation effects. Specifications for a 200mA load pulse as V
Note 7: V
Note 8: Comparator threshold is expressed in terms of a voltage differential at the Adjust terminal below the nominal reference
voltage measured 6V input. To express these thresholds in terms of output voltage change, multiply the error amplifier gain =
V
the output drops by 95mVx 5V/ 1.240V = 383mV. Threshold remain constant as a percent of V
dropout warning occurring at typically 5% below nominal, 7.7% guaranteed.
