Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device
reliability. The absolute maximum ratings are stress ratings only.

Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to Absolute Maximum Ratings.

Notes:
2.
A high input capacitor value is required for limiting input voltage drop during bypass transitions or during large
output voltage transitions. Ensure the input capacitor value is greater than the output capacitor’s. See the inrush
current specifications below.

Notes:
4.
Thermal Resistance, Junction-to-Ambient, measured according to JEDEC 2S2P PCB (and zero air flow). θJA for
JEDEC 1S0P PCB (and zero air flow) = 210°C/W.
5.
Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any
allowable ambient temperature is PD=[TJ(max) - TA ] / θJA.
