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. DC CHARACTERISTICS Electrical Specifications: Unless otherwise noted, VIN = VR +1V, IOUT1 = IOUT2 = 100 µA, CIN = 4.7 µF, COUT1 = COUT2 = 1 µF, CBYPASS = 10 nF, SHDN > VIH, TA = +25°C. Boldface type specifications apply for junction temperatures of -40°C to +125°C.

Load regulation is tested over a load range from 0.1 mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal regulation specification. 5: Thermal regulation is defined as the change in output voltage at a time t after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a current pulse equal to ILMAX at VIN = 6V for t = 10 ms. 6: Dropout voltage is defined as the input-to-output voltage differential at which the output voltage drops 2% below its value measured at a 1V differential. 7: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the thermal resistance from junction-to-air (i.e., TA, TJ, θJA). Exceeding the maximum allowable power dissipation causes the device to initiate thermal shutdown . |
