Note 5:
The LT6107 output is an open collector current source. The output current of the LT6107 must be limited to insure that the power minimum output voltage scales directly with the ratio R dissipation in the LT6107 does not allow the die temperature to exceed OUT/10k.

Note 2:
Junction temperatures greater than 125°C will promote SENSE(MAX) is the maximum sense voltage for which the Electrical Characteristics will apply. Higher voltages can affect performance but will accelerated aging. The LT6107 has demonstrated typical life beyond 1000 not damage the part provided that the output current of the LT6107 does hours at 150°C. LT6107H is guaranteed to meet specified performance not exceed the allowable power dissipation as described in Note 1. from –40°C to 150°C. LT6107MP is guaranteed to meet specified performance from –55°C to 150°C. TYPICAL PERFORMANCE CHARACTERISTICS
