NOTES:
3. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in V_OUT is divided by the
temperature range: (-40°C to +85°C = +125°C, or -40°C to +105°C = +145°C for the ISL60002-33).
4. Thermal Hysteresis is the change in V_OUT measured @ T_A = +25°C after temperature cycling over a specified range, ΔT_A, V_OUT is read initially
at T_A = +25°C for the device under test. The device is temperature cycled and a second V_OUT measurement is taken at +25°C. The difference
between the initial V_OUT reading and the second V_OUT reading is then expressed in ppm. For ΔT_A = +125°C, the device under is cycled from
+25°C to +85°C to -40°C to +25°C, and for ΔT_A = +145°C, the device under is cycled from +25°C to +105°C to -40°C to +25°C
5. Long term drift is logarithmic in nature and diminishes over time. Drift after the first 1000 hours will be approximately 10ppm.
6. Short Circuit Current (to V_CC) for ISL60002-25 at V_IN = 5.0V and +25°C is typically around 30mA. Shorting V_OUT to V_CC is not recommended
due to risk of resetting the part.
