ELECTRICAL CHARACTERISTICS

LM150: -55

oC

≤ Tj ≤ 150 oC, VI -VO = 5V, IO = 1.5A

LM250: -25

oC

≤ Tj ≤ 150 oC, VI -VO = 5V, IO = 1.5A

LM350: 0

oC

≤ Tj ≤ 150 oC, VI -VO = 5V, IO = 1.5A

Although power dissipation is internally limited, these specifications apply to power dissipation up to

30W (unless otherwise specified).
