Typ. Max. 15 V 12 V 10 V 0 125 °C Note 2. Range over which the device is functional. ELECTRICAL CHARACTERISTICS (Unless otherwise specified: 0°C ≤ T J ≤ 125°C, I MAX = 0.8A for the LX8117-xx, I MAX = 1.0A for the LX8117A-xx, and I MAX = 1.2A for the LX8117B-xx.) Notes: 3. 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. 4. 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. 5. Minimum load current is defined as the minimum output current required to maintain regulation. Parameter Symbol Test Conditions Units LX8117 / 17A / 17B-00 Min. Typ. Max.
