Regulated 5V USB Charge Pump with
Programmable Current Limit
ELECTRICAL CHARACTERISTICS (continued)
(VIN = SHDN = 3V, CIN = 4.7µF, CX = 0.68µF, CEXT = 6.8µF, COUT = 4.7µF, RCS = 0.4Ω, TA = 0°C to +70°C, unless otherwise noted.
Typical values are at TA = +25°C.)

Note 1: When the input exceeds 4.25V, the power dissipation on the chip exceeds the maximum rating if the output current is 125mA.
Note 2: The MIN/MAX limits are 100% production tested at +25°C and +70°C, and guaranteed by design at 0°C.
Note 3: IOUT is output current flowing from CEXT.
Note 4: The delay from the fault event to the assertion of FAULT. Fault delays are specified with either a current fault or a voltage
fault, but not both simultaneously.
Note 5: The delay from the removal of the fault event to the deassertion of FAULT.
