Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality

should not be assumed, damage may occur and reliability may be affected.

Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond

the Recommended Operating Ranges limits may affect device reliability.

3. The input capacitor must be large enough to limit the input voltage drop during GSM bursts, bypass transitions, and large output voltage

transitions.

4. Regulator requires only one 4.7 mF.

Junction−to−Ambient Thermal Resistance (Note 5)

°C/W

5. Junction−to−ambient thermal resistance is a function of application and board layout. This data is measured with four−layer 2s2p boards

with vias in accordance to JESD51− JEDEC standard. Special attention must be paid not to exceed junction temperature T at a given

J(MAX)

ambient temperature T .
