This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS Electrical Specifications: Unless otherwise specified, all limits are established for V IN = VR + 1.0V, Note 1, COUT = 1 µF (X7R), CIN = 1 µF (X7R), VSHDN = VIN, TA = +25°C.

For example: VR = 1.8V, 2.5V, 3.0V, 3.3V, or 5.0V. The input voltage VIN = VR + 1.0V or ViIN = 2.0V (whichever is greater); IOUT = 100 µA. 3: TCVOUT = (VOUT-HIGH - VOUT-LOW) *10 6 / (V R * ΔTemperature), VOUT-HIGH = highest voltage measured over the temperature range. VOUT-LOW = lowest voltage measured over the temperature range. 4: Load regulation is measured at a constant junction temperature using low duty cycle pulse testing. Changes in output voltage due to heating effects are determined using thermal regulation specification TCVOUT. 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its measured value with an applied input voltage of VR + 1.0V or 2.0V, whichever is greater. |
