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 sys- tems, the TC1014’s CMOS construction eliminates wasted ground current, significantly extending battery life. Total supply current is typically 50 µA 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 com- pensation for fast response to step changes in load. Supply current is reduced to less than 1 µA when the shutdown input is low. The TC1014 also incorporates both over-tempera- ture and over-current protection. The TC1014 is stable with an output capacitor of only 1 µF and has a maximum output current of 100mA. For higher output versions, please see the TC1107, TC1108, TC1173 (IOUT = 300mA) data sheets. 1 µF 470pF Reference Bypass Cap (Optional) Shutdown Control (from Power Control Logic) TC1014 VIN 1 2 34 5 VIN VOUT Bypass SHDN GND VOUT PIN CONFIGURATION ORDERING INFORMATION Output Junction Part No. Voltage **(V) Package Temp.
