TC1014/TC1015/TC1185 50 mA, 100 mA and 150 mA CMOS LDOs with Shutdown and Reference Bypass Features: General Description Low Supply Current (50 A, typical) The TC1014/TC1015/TC1185 are high accuracy (typically 0.5%) CMOS upgrades for older (bipolar) Low Dropout Voltage Low Dropout Regulators (LDOs) such as the LP2980. Choice of 50 mA (TC1014), 100 mA (TC1015) Designed specifically for battery-operated systems, the and 150 mA (TC1185) Output devices CMOS construction eliminates wasted ground High Output Voltage Accuracy current, significantly extending battery life. Total supply Standard or Custom Output Voltages current is typically 50 A at full load (20 to 60 times Power-Saving Shutdown Mode lower than in bipolar regulators). Reference Bypass Input for Ultra Low-Noise The devices key features include ultra low-noise Operation operation (plus optional Bypass input), fast response to Overcurrent and Overtemperature Protection step changes in load, and very low dropout voltage, typically 85mV (TC1014), 180mV (TC1015), and Space-Saving 5-Pin SOT-23 Package 270mV (TC1185) at full-load. Supply current is Pin-Compatible Upgrades for Bipolar Regulators reduced to 0.5 A (max) and V falls to zero when OUT Standard Output Voltage Options: the shutdown input is low. The devices incorporate both - 1.8V, 2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 3.0V, overtemperature and overcurrent protection. 3.3V, 3.6V, 4.0V, 5.0V The TC1014/TC1015/TC1185 are stable with an output Applications: capacitor of only 1 F and have a maximum output current of 50 mA, 100 mA and 150 mA, respectively.

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 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, excluding load or line regulation effects. Specifications are for a current pulse equal to I at V = 6V for T = 10 ms. LMAX IN 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., T , T , ). Exceeding the maximum allowable power dissipation causes the device to A J JA initiate thermal shutdown.
