Caution:

Stresses beyond the ratings specified in

“Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only

rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification

is not implied.

Note1: When CS pin voltage < 0V ~ -2V, the current of ICS must be < 100mA in 10ms.

Note2: When OUT pin voltage < -0.3V ~ -1V, the current of IOUT must be < 20mA in 1s and the pin has to connect a resistor with the

values between 47Ω~150Ω in series.
