IO = 0 mA, TJ = 25 °C

IO = 0 to 1.5 A, VI = 4.9 to 30 V

IO = 0 mA, VI = 4.9 to 18 V,

TJ = 25 °C

IO = 0 mA, VI = 4.9 to 18 V

IO = 0 to 1.5 A, TJ = 25 °C

IO = 0 to 1.5 A

IO = 1.5 A

VI ≤ 30 V

VI - VO = 5 V

VI - VO = 25 V

TA = 25 °C, 30 ms pulse

f = 120 Hz, CO = 25 µF, IO = 1.5 A

VI = 8.3 ± 3 V

TA = 25 °C, f =10 Hz to 10 kHz

S Long term stability

TA = 125 °C, 1000 Hrs
