The dropout voltage is 0.7V at 2A output current. The typical qui- escent current is 1.8mA. Furthermore, the quiescent current is smaller when the regulator is in the dropout mode. Familiar regulator features such as over tem- perature and over current protection circuits are provided to prevent it from being damaged by abnormal operating conditions. A Ven pin is pro- vided to disable the output when needed. Ordering Information PIN OPTION ORDER NUMBER MARKING TEMP.
