Parasitic diodes exist internally between IN, OUT, SENSE, BIAS, BIASF, VO0, VO1, VO2, MARG, EN, VIOC, TEMP,

IMON, PG, REF pins, and GND. Do not drive these pins more than 0.3V below the GND pin during a fault

condition. These pins must remain at a voltage more positive than GND during normal operation.

The LT3073A is tested and specified under pulse load conditions such that TJ ≈ TA (ambient temperature). The

LT3073A is tested at TA = 25°C. Performance of the LT3073A over the full –40°C to 125°C operating temperature

range is assured by design, characterization, and correlation with statistical process controls. The LT3073A is

guaranteed over the full –40°C to 125°C operating junction temperature range.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These

are stress ratings only, functional operation of the product at these or any other conditions above those indicated in

the operational section of this specification is not implied. Operation beyond the maximum operating conditions for

extended periods may affect product reliability.

Thermal Resistance

Thermal performance is directly linked to PCB design and operating environment. Therefore, close attention to

PCB thermal design is required.

ESD Caution

ESD (electrostatic discharge) sensitive device. Charged devices and circuit boards can

discharge without detection. Although this product features patented or proprietary

protection circuitry, damage may occur on devices subjected to high energy ESD. Therefore,

proper ESD precautions should be taken to avoid performance degradation or loss of

functionality.
