Note 1: Output or reference voltage temperature coefficients defined as the worst case voltage change divided by the tatal
temperature range.
Note 2: Regulations is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output
voltage due to heating effects are covered under the specification for thermal regulation.
Note 3: Line regulation is tested at 125℃ for IL = 5mA. For IL = 100μA and TJ = 125℃, line regulation is guaranteed by desigh to
0.2%. for 13V ≤ Vin ≤26V.
Note 4: Dropout voltage is defined as the input to output differential at which the output voltage drops2% below its nominal value
measured at 1V differential.
Note 5: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the ground pin
current and output load current.
Note 6: Thermal regulation is the change in output voltage at a time T after a change in power dissipation, excluding load or line
regulation effects. Specifications are for a 200mA load pulse(3W pulse) for T = 10ms.
Note 7: Vref ≤ Vou t≤ (Vin-1V), 2.3V ≤ Vin ≤26V, 100μA ≤ IL ≤ 400mA, TJ ≤ TJMAX .
Note 8: 2V ≤ Vshutdown, Vin ≤ 26V, Vout = 0V
