How much current is LTC1695 maximum output current ?

Question

Dear all, 
 How much current is LTC1695 maximum output current @ Vin=3.3V, Vout=3V ?? 
 My loading is a DC Fan 3V/90mA, 
 I have 3 questions: 
 a. Does it can work normally if Vin=3.3V ???? ( i can found current limit value @ Vin=3.3V in spec) 
 b. if Vin=5V, Vout=3V, Can the output current over 150 mA ?? 
 c. I saw the EC table in spec.... about UVLO item ( rising maximum is 3.5V), but the curve maximum is 2.9xV....

For my own records can you note what company this project is for and what’s annual usage? 
 
 The LTC1695 is designed to drive 5V fans, not 3.3V as mentioned on page 11 D/S. You can set Vout to 3.3V, though, as mentioned on page 17 D/S. 
 Expect 50⁰C temperature increase at these conditions, see “Junction Temperature Increase vs Load Current” graph and Thermal Considerations page 14. 
 UVLO typical is 2.9V.
