Notes:
1. Option 06 and 07 is rated for 1A output current. All other options are rated for 800mA output current.
2. VOUT is limited to the maximum voltage for all VSEL codes greater than the maximum VOUT listed.
3. VOUT may be programmed down 100mV for option 07. Performance below 0.75V is not guaranteed.
4.
All packages are “green” per JEDEC: J-STD-020B standard. The “X” designator specifies tape and reel packaging.

Notes:
5. Minimum L incorporates both tolerance, temperature, and partial saturation effects (L decreases with increasing current).
6. Minimum C is a function of initial tolerance, maximum temperature, and the effective capacitance being reduced due to
frequency, dielectric, and voltage bias effects.
