Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: See thermal regulation specification for changes in output voltage due to heating effects. Load regulation and line regulation are measured at a constant junction temperature by low duty cycle pulse testing. Note 3: Dropout voltage is specified over the full output current range of the device. Dropout voltage is defined as the minimum input/output differential measured at the specified output current. Test points and limits are also shown on the Dropout Voltage curve. Note 4: Minimum load current is defined as the minimum output current required to maintain regulation. ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TJ = 25°C. TYPICAL PERFORMANCE CHARACTERISTICS |
