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 55
μ
A 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 0.5
μ
A
(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 1
μ
F and have a
maximum output current of 50mA, 100mA and 150mA,
respectively. This LDO Family also features a fast
response time (60
μ
sec typically) when released from
shutdown.
