MICROCHIP TC1185 Manuals

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/TC1185 are high accuracy (typically ±0.5%) CMOS upgrades for older (bipolar) low dropout regulators such as the 7805 and 78L05. They provide 50mA (TC1014), 100mA (TC1015) and 150mA (TC1016) output current and can provide standard or custom output voltages in the 1.8V to 5.0V range.
