VIN +0.3V to -0.3V *Stresses above those listed under “Absolute Maxi- mum Ratings” may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operation sections of the specifications is not implied. Exposure to Absolute Maximum Rating conditions for extended periods my affect device reliability. TC2054/2055/2186 ELECTRICAL SPECIFICATIONS Electrical Characteristics: VIN =VR +1V, IL =100µA, CL =3.3µF, SHDN >VIH,TA = 25°C, unless otherwise noted.

For example: VR = 1.8V, 2.7V, 2.8V, 2.85V, 3.0V, 3.3V. 3: TCVOUT = 4: Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range from 1.0mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal regulation specification. 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value at a 1V differential. 6: Thermal Regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, exclud- ing load or line regulation effects. Specifications are for a current pulse equal to IMAX at VIN = 6V for T = 10msec. 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). 8: Hysteresis voltage is referenced by VR. 9: Time required for VOUT to reach 95% of VR (output voltage setting), after VSHDN is switched from 0 to VIN.
