elecTrical characTerisTics Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
IFULL_LOAD is defined in the current limit curves. The IFULL_LOAD may cause permanent damage to the device. Exposure to any Absolute curve is defined as the minimum value of current limit as a function of Maximum Rating condition for extended periods may affect device input-to-output voltage. Note that the 60W power dissipation for the reliability and lifetime. LT1083 (45W for the LT1084 (K, P), 30W for the LT1084 (T), 30W for the
Note 2:
See thermal regulation specifications for changes in output voltage LT1085) is only achievable over a limited range of input-to-output voltage. due to heating effects. Load and line regulation are measured at a constant
Note 5:
Dropout voltage is specified over the full output current range of junction temperature by low duty cycle pulse testing. the device. Test points and limits are shown on the Dropout Voltage curve.
Note 3:
Line and load regulation are guaranteed up to the maximum power
Note 6:
For LT1083 IFULL_LOAD is 5A for –55°C ≤ TJ < – 40°C and 7.5A for dissipation (60W for the LT1083, 45W for the LT1084 (K, P), 30W for the TJ ≥ –40°C. LT1084 (T) and 30W for the LT1085). Power dissipation is determined by
Note 7:
1.7V ≤ (VIN – VOUT) ≤ 25V for LT1084 at –55°C ≤ TJ ≤ – 40°C. the input/output differential and the output current. Guaranteed maximum
Note 8:
Dropout is 1.7V maximum for LT1084 at –55°C ≤ T power dissipation will not be available over the full input/output voltage J ≤ –40°C. range.
Note 9:
The LT1083/LT1084/LT1085 regulators are tested and specified under pulse load conditions such that TJ ≅ TA. The C-grade LT1083/ LT1084/LT1085 are 100% tested at 25°C.The I-grade LT1084/LT1085 are guaranteed over the full –40°C to 125°C operating ambient temperature range. 108345fh 6 For more information www.linear.com/LT1083 Document Outline Features Applications Typical Application Description Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Typical Performance Characteristics Block Diagram Applications Information Typical Application Package Description Revision History Typical Applications Related Parts
