LM1117-N ELECTRICAL CHARACTERISTICS
Typicals and limits appearing in normal type apply for T_J = 25°C. Limits appearing in Boldface type apply over the entire
junction temperature range for operation, 0°C to 125°C.

(1) All limits are ensured by testing or statistical analysis.
(2) Typical Values represent the most likely parametric normal.
(3) Load and line regulation are measured at constant junction room temperature.
(4) The dropout voltage is the input/output differential at which the circuit ceases to regulate against further reduction in input voltage. It is
measured when the output voltage has dropped 100mV from the nominal value obtained at V_IN = V_OUT +1.5V.
