TC1054/TC1055/TC1186 ELECTRICAL SPECIFICATION S (CONTINUED) Electrical Characteristics: VIN =VOUT +1V, IL =100µA, CL =3.3µF, SHDN >VIH,TA = 25°C, unless otherwise noted. Boldface type specifications apply for junction temperatures of -40°C to +125°C. Symbol Parameter Min Typ Max Units Test Conditions SHDN Input VIH SHDN Input High Threshold 45 — — %VIN VIN =2.5V to 6.5V VIL SHDN Input Low Threshold — — 15 %VIN VIN =2.5V to 6.5V ERROR Output VIN MIN Minimum VIN Operating Voltage 1.0 — — V VOL O utput Logic Low Voltage — — 400 mV 1 mA Flows to ERROR VTH ERROR Threshold Voltage — 0.95 x VR — V SeeFigure3-2 VHYS ERROR Positive Hysteresis — 50 — mV Note 7 Note 1: VR is the regulator output voltage setting. For example: VR = 1.8V, 2.5V, 2.7V, 2.85V, 3.0V, 3.3V, 3.6V, 4.0V, 5.0V. 2: 3: Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range from 0.1mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal regulation specification. 4: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value. 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 msec. 6: 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. Please see Section 4.0 Thermal Considerations for more details. 7: Hysteresis voltage is referenced by VR. 8: The minimum VIN has to justify the conditions: VIN ≥ VR +VDROPOUT and VIN ≥ 2.7V for IL = 0.1mA to IOUTMAX.
