The TC1014/TC1015/TC1185 are high accuracy (typical ±0.5%) CMOS upgrades for older (bipolar) Low Dropout Regulators (LDOs) such as the LP2980. Designed specifically for battery-operated systems, the devices’ 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). The devices’ key features include ultra low-noise operation (plus optional Bypass input), fast response to step changes in load, and very low dropout voltage, typically 85 mV (TC1014), 180 mV (TC1015), and 270 mV (TC1185) at full-load. Supply current is reduced to 0.5 µA (max) and VOUT falls to 1% of input voltage or less under full load.
The TC1014, TC1015, and TC1185 are CMOS low‑dropout (LDO) regulators designed for battery‑operated systems, portable computers, medical instruments, and other low‑power applications. They offer selectable output currents of 50 mA, 100 mA, or 150 mA and provide ultra‑low‑noise operation with optional reference bypass.
Key characteristics include low quiescent current (typical 50 nA), shutdown mode that reduces supply current to near zero, and a compact 5‑pin SOT‑23 package. The devices feature over‑current and over‑temperature protection, and are pin‑compatible upgrades for older bipolar LDOs such as the LP2980.
