  TC2054/2055/2186 Datasheet


The TC2054, TC2055, and TC2186 are high accuracy (typically ±0.4%) CMOS upgrades for older (bipolar) low dropout regulators. Designed specifically for battery-operated systems, the devices’ total supply current is typically 55µA at full load ( 20 to 60 times lower than in bipolar regulators!). The devices’ key features include ultra low noise operation, very low dropout voltage - typically 45mV (TC2054); 90mV (TC2055); and 140mV (TC2186) at full load - and fast response to step changes in load. An error output (ERROR) is asserted when the devices are out-of-regulation (due to a low input voltage or excessive output current). Supply current is reduced to 0.5µA (max) and both VOUT and ERROR are disabled when the shutdown input is low. The devices also incorporate over-current protection. The TC2054, TC2055, and TC2186 are stable with a low ESR output capacitor of only 1µF and have a maximum output current of 50mA, 100mA, and 150mA, respectively. This LDO Family also features a fast response time (60msec typically) when released from shutdown.
