Overview
50mA CMOS LDO WITH SHUTDOWN AND REFERENCE BYPASS PRELIMINARY INFORMATION TC1014 TC1014 50mA CMOS LDO WITH SHUTDOWN AND REFERENCE BYPASS FEATURES s s s s s s s s s s Zero Ground Current for Longer Battery Life! Very Low Dropout Voltage Guaranteed 50mA Output High Output Voltage Accuracy Standard or Custom Output Voltages Power-Saving Shutdown Mode Reference Bypass Input for Ultra Low-Noise Operation Over-Current and Over-Temperature Protection Space-Saving SOT-23A-5 Package Pin Compatible Upgrade for MIC5205 and NSC2980 GENERAL DESCRIPTION The TC1014 is a high accuracy (typically ±0.
5%) CMOS upgrade for older (bipolar) low dropout regulators such as the LP2980.
Designed specifically for battery-operated systems, the TC1014’s CMOS construction eliminates wasted ground current, significantly extending battery life.
Total supply current is typically 50µA at full load (20 to 60 times lower than in bipolar regulators!).
TC1014 key features include ultra low-noise operation (plus optional Bypass input); very low dropout voltage (typically 95mV at full load) and internal feed-forward compensation for fast response to step changes in load.
Supply current is reduced to less than 1µA when the shutdown input is low.
The TC1014 also incorporates both over-temperature and over-current protection.
The TC1014 is stable with an output capacitor of only 1µF and has a maximum output current of 100mA.
For higher output versions, please see the TC1107, TC1108, TC1173 (IOUT = 300mA) data sheets.
