(1) Unless otherwise specified all limits ensured for V_IN = (V_ONOM + 1)V, I_L = 100µA and C_L = 1µF. Limits appearing in boldface type apply
over the entire junction temperature range for operation. Limits appearing in normal type apply for T_A = T_J = 25°C.
(2) Ensured and 100% production tested.
(3) Ensured but not 100% production tested. These limits are not used to calculate outgoing AQL levels.
(4) Output or reference voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
(5) Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to
heating effects are covered under the specification for thermal regulation.
(6) For I_L = 100µA and T_J = 125°C, line regulation is ensured by design to 0.2%. See Typical Performance Characteristics for line regulation
versus temperature and load current.
(7) Dropout Voltage is defined as the input to output differential at which the output voltage drops 100 mV below its nominal value
measured at 1V differential. At very low values of programmed output voltage, the minimum input supply voltage of 2V (2.3V over
temperature) must be taken into account.
