Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. 60 second maximum above 183°C. ELECTRICAL CHARACTERISTICS (0°C ≤ TA ≤ 70°C; 0°C ≤ TJ ≤ 150°C; VSENSE = VOUT and VADJ = 0 V; unless otherwise specified.) Characteristic Test Conditions Min Typ Max Unit CS5253−1 Reference Voltage VCONTROL = 2.75 V to 12 V, VPOWER = 2.05 V to 5.5 V, IOUT = 10 mA to 3.0 A 1.237 (−1.0%) 1.250 1.263 (+1.0%) V Line Regulation VCONTROL = 2.5 V to 12 V, VPOWER = 1.75 V to 5.5 V, IOUT = 10 mA − 0.02 0.2 % Load Regulation VCONTROL = 2.75 V, VPOWER = 2.05 V, IOUT = 10 mA to 3.0 A, with Remote Sense − 0.04 0.3 % Minimum Load Current (Note 2) VCONTROL = 5.0 V, VPOWER = 3.3 V, DVOUT = +1.0% − 5.0 10 mA Control Pin Current (Note 3) VCONTROL = 2.75 V, VPOWER = 2.05 V, IOUT = 100 mA VCONTROL = 2.75 V, VPOWER = 2.05 V, IOUT = 3.0 A − − 6.0 35 10 120 mA mA Adjust Pin Current VCONTROL = 2.75 V, VPOWER = 2.05 V, IOUT = 10 mA − 60 120 mA Current Limit VCONTROL = 2.75 V, VPOWER = 2.05 V, DVOUT = −1.0% 3.1 4.0 − A Short Circuit Current VCONTROL = 2.75 V, VPOWER = 2.05 V, VOUT = 0 V 2.0 3.5 − A 2. The minimum load current is the minimum current required to maintain regulation. Normally the current in the resistor divider used to set the output voltage is selected to meet the minimum load current requirement. 3. The VCONTROL pin current is the drive current required for the output transistor. This current will track output current with roughly a 1:100 ratio. The minimum value is equal to the quiescent current of the device. |
