Note 1: All voltages are referenced to ground. Currents entering the IC are specified positive and currents exiting the IC are negative.
Note 2: This supply range guarantees that the LOAD voltage is not clamped by the overvoltage limit.
Note 3: Supply current specified with no load on the LOAD pin.
Note 4: V_LOFF voltage specified with a 2.5mA load applied to LOAD.
Note 5: Not production tested. Guaranteed by design.
Note 6: I_SCL is the current limit when the output voltage is initially ramping up.
Note 7: I_OVL is the current limit after the output voltage ramping is complete.
Typical Operating Characteristics
