7.3.5 Low-Power Mode

At light loads and high input voltages (VIN > approximately 8 V, such that the charge pump is off), the device operates in low-power mode and the quiescent current consumption is reduced to 25 µA (typical) as shown in Table 1.

Table 1. Typical Quiescent Current Consumption

IOUT Charge Pump ON Charge Pump OFF
IOUT < approximately 2 mA
(Light load)		 250 µA 35 µA
(Low-power mode)
IOUT > approximately 2 mA
(Heavy load)		 280 µA 70 µA
