Recommended Operating Conditions (3)

Supply voltage (VIN) ...........................2.6V to 6V

Output voltage (VOUT)......................0.6V to 1.1V

Operating junction temp........... -40°C to +125°C

Thermal Resistance

θJA

θJC

QFN-12 (2mmx2mm) ............. 70....... 15.....°C/W

NOTES:

Exceeding these ratings may damage the device.

The maximum allowable power dissipation is a function of the

maximum junction temperature TJ (MAX), the junction-to-

ambient thermal resistance θJA, and the ambient temperature

TA. The maximum allowable continuous power dissipation at

any ambient temperature is calculated by PD (MAX) = (TJ

(MAX)-TA)/θJA. Exceeding the maximum allowable power

dissipation produces an excessive die temperature, causing

the regulator to go into thermal shutdown. Internal thermal

shutdown circuitry protects the device from permanent

damage.

The device is not guaranteed to function outside of its operating

conditions.

Measured on JESD51-7, 4-layer PCB.
