... On-chip thermal lim- iting provides protection against any combination of over- load that creates excessive junction temperatures. The LT1587-1.5 is available in both the through-hole and surface mount versions of the industry standard 3-pin TO-220 power package. , LTC and LT are registered trademarks of Linear Technology Corporation. ...

... Note 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. Note 2: Line and load regulation are guaranteed up to the maximum power dissipation (17W for the LT1587-1 package). Power 2 U RATINGS Storage Temperature Range ................. – ...

... Only with large values of output capacitance, such as 1000 F to 5000 F, and with the input pin instantaneously shorted to ground can dam- age occur. A crowbar circuit at the input of the LT1587-1.5 can generate those levels of current, and a diode from output to input is then recommended. This is shown in CAPACITANCE Figure 2 ...
