Note 1: TC V_OUT = (V_OUTMAX – V_OUTMIN) x 10⁶
V_OUT x ΔT
2: Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range
from 0.1 mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal
regulation specification.
3: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value.
4: Thermal Regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or
line regulation effects. Specifications are for a current pulse equal to I_LMAX at V_IN = 6V for T = 10 ms.
5: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the
thermal resistance from junction-to-air (i.e., T_A, T_J, θ_JA). Exceeding the maximum allowable power dissipation causes the device to initiate
thermal shutdown. Please see Section 5.0 “Thermal Considerations” for more details.
6: The minimum V_IN has to justify the conditions: V_IN ≥ V_R + V_DROPOUT and V_IN ≥ 2.7V for I_L = 0.1 mA to I_OUTMAX.
