Output voltage (VOUT)................... 0.61V to 4.5V

Operating junction temp. (TJ). .. -40°C to +125°C

Thermal Resistance

(4)

θJA

θJC

QFN-14 (3mmx4mm) ............ 48....... 10 ... °C/W

NOTES:

1) Exceeding these ratings may damage the device.

2) The maximum allowable power dissipation is a function of the

maximum junction temperature TJ(MAX),

the junction-to-

a

mbient thermal resistance θ

JA, 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.

3) The device is not guaranteed to function outside of its

operating conditions.

4) Measured on JESD51-7, 4-layer PCB.
