General Description
The TC2054, TC2055 and TC2186 are high accuracy
(typically ±0.4%) CMOS upgrades for older (bipolar)
low dropout regulators. Designed specifically for bat-
tery-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 oper-
ation, 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 exces-
sive output current). Supply current is reduced to 0.5µA
(max) and both V
OUT
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 ceramic output capacitor of 1µF and have a
maximum output current of 50mA, 100mA and 150mA,
respectively. This LDO Family also features a fast
response time (60µsec typically) when released from
shutdown.
