† Notice: Stresses above those listed under “Maximum

Ratings” may cause permanent damage to the device.

This is a stress rating only and functional operation of

the device at those or any other conditions above those

indicated

the

operational

sections

this

specification is not intended. Exposure to maximum

rating conditions for extended periods may affect

device reliability.

OUT (1 mA).

For VIN > VOUT, VOUT will not remain in regulation.

IQOUT is measured at VOUT, VOUT is external supplied for VOUT > VIN (device is not switching), IQIN is

measured at VIN pin during Sleep period, no load.
