(2) Under no conditions should the output voltage be allowed to fall below zero volts. (3) An extended output voltage range to 10 V is possible with changes to the typical application schematic. Also, some system specifications are not achieved for output voltages greater than 6 V. Consult the factory for further information. (4) High junction temperatures degrade operating lifetimes. Operating lifetime is de-rated for junction temperatures greater than 125°C. 7.3 Recommended Operating Conditions over the recommended operating junction temperature range of –40°C to 150°C (unless otherwise noted) MIN NOM MAX UNIT Input voltage(1) 3.9 36 V Output voltage : fixed 5 V(2) 0 5 V Output voltage : fixed 3.3 V(2) 0 3.3 V Output voltage adjustment range: ADJ(2)(3) 3.3 10 V Output current for LM53603 0 3 A Output current for LM53602 0 2 A RESET pin current 0 1 mA Operating junction temperature(4) –40 150 °C (1) The values given in this table are only valid for comparison with other packages and cannot be used for design purposes. These values were calculated in accordance with JESD 51-7, and simulated on a 4-layer JEDEC board. They do not represent the performance obtained in an actual application. For design information please see the Maximum Ambient Temperature section.
