Absolute Maximum Ratings

(Unless otherwise indicated: Ta=25℃)

Note:These are just the limit parameters.Beyond the range specified in the Absolute Maximum Ratings may cause serious damage to the equipment.Long exposure to extreme conditions may affect the reliability of the device.

(1)Increasing the welding area of package is beneficial to increase power consumption

Notes:

1.VOUT(S): Output voltage when VIN= Vout +2V, Iout=1 mA.

2.VDROP=Vin1 -（Vout(S)× 0.98）where Vin 1 is the input voltage when Vout = Vout (S)× 0.98.

3.ILIM : Output current when Vin=Vout (S)+2V and Vout = 0.95*Vout (S).
