VIN +0.3V to – 0.3V Maximum Junction Temperature ...................... ............ 150°C † Notice: Stresses above those listed under "Absolute Maximum 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 may affect device reliability. ELECTRICAL CHARACTERISTICS Electrical Specifications: Unless otherwise specified, VIN = VR + 1V, IL = 100 µA, COUT = 3.3 µF, SHDN > VIH, TA = +25°C. BOLDFACE type specifications apply for junction temperature of -40°C to +125°C. Parameters Sym Min Typ Max Units Conditions Input Operating Voltage VIN 2.7 — 6.0 V Note 1 Maximum Output Current IOUTMAX 50 —— mA TC2014 100 —— TC2015 150 —— TC2185 Output Voltage VOUT VR – 2.0% VR ± 0.4% VR + 2.0% V Note 2 VOUT Temperature Coefficient TCVOUT — 20 — ppm/°C Note 3 — 40 — Line Regulation ΔVOUT/ΔVIN —0.05 0.5 %(VR + 1V) < VIN < 6V Load Regulation (Note 4) ΔVOUT/VOUT -1.0 0.33 +1.0 % TC2014;TC2015:IL = 0.1 mA to IOUTMAX -2.0 0.43 +2.0 TC2185:IL = 0.1 mA to IOUTMAX (Note 4) Dropout Voltage VIN – VOUT —2 — mV Note 5 IL = 100 µA —45 70 IL = 50 mA —90 140 TC2015; TC2185 IL = 100 mA — 140 210 TC2185 IL = 150 mA Supply Current IIN —55 80 µA SHDN = VIH, IL = 0 Shutdown Supply Current IINSD — 0.05 0.5 µA SHDN = 0V Power Supply Rejection Ratio PSRR — 55 — dB F ≤ 1 kHz, Cbypass = 0.01 µF Output Short Circuit Current IOUTSC — 160 300 mA VOUT = 0V Note 1: The minimum VIN has to meet two conditions: VIN = 2.7V and VIN = VR + VDROPOUT. 2: VR is the regulator output voltage setting. For example: VR = 1.8V, 2.7V, 2.8V, 2.85V, 3.0V, 3.3V. 3: 4: Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range from 1.0 mA 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. 6: 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 IMAX at VIN = 6V for T = 10 ms. 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: Time required for VOUT to reach 95% of VR (output voltage setting), after VSHDN is switched from 0 to VIN.
