(TO-220): Control Circuitry/Power Transistor — — 0.65/2.7 °C/W Resistance TCL1585 “A” pkg. (TO-220): Control Circuitry/Power Transistor — — 0.7/3.0 °C/W (Junction to TCL1585 “E” pkg. (TO-263): Control Circuitry/Power Transistor — — 0.7/3.0 °C/W Case, ΘJA) TCL1587 “A” pkg. (TO-220): Control Circuitry/Power Transistor — — 0.7/3.0 °C/W TCL1587 “E” pkg. (TO-263): Control Circuitry/Power Transistor — — 0.7/3.0 °C/W NOTES: 1. See thermal regulation specifications for changes in output voltage due to heating effects. Load and line regulation are measured at a constant junction temperature by low duty cycle pulse testing. 2. Load and line regulation are guaranteed up to the maximum power dissipation (25W for the TCL1584 in “A” pkg., 26.5W for the TCL1585 in “A” pkg., 18W for the TCL1587 in “A” pkg.). Power dissipation is determined by input/output voltage differential and output current. Guaranteed maximum output current/power will not be available over full input/output voltage range. 3. IFULL LOAD is defined as the maximum value of output load current as a function of input-to-output voltage. IFULL LOAD is a nominal 7A for TCL1584, decreasing to approximately 3A as VIN – VOUT increases from 3V to 7V. For all other fixed voltage TCL1585’s, IFULL LOAD is 4A. For the TCL1587, IFULL LOAD is 3A. The TCL1585 and 1587 have constant current limit with respect to VIN and VOUT. |
