General Description

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 55 µA at full load (20 to 60 times

lower than in bipolar regulators).

The devices’ key features include low noise operation,

low dropout voltage – typically 45 mV (TC2054); 90 mV

(TC2055); and 140 mV (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

0.5 µA (maximum) and both V

OUT

and ERROR are

disabled when the shutdown input is low. The devices

also incorporate overcurrent and overtemperature

protection.

The TC2054, TC2055 and TC2186 are stable with a

low esr ceramic output capacitor of 1 µF and have a

maximum output current of 50 mA, 100 mA and

150 mA, respectively. This LDO Family also features a

fast response time (60 µs typically) when released from

shutdown.
