General Description
The TC1054, TC1055 and TC1186 are high accuracy
(typically ±0.5%) CMOS upgrades for older (bipolar)
low dropout regulators. Designed specifically for
battery-operated
construction minimizes ground current, 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 low noise operation,
low dropout voltage – typically 85 mV (TC1054),
180 mV (TC1055) and 270 mV (TC1186) 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). ERROR can be used as a low battery
warning or as a processor RESET signal (with the
addition of an external RC network). Supply current is
reduced to 0.5 µA (max), with both V
disabled when the shutdown input is low. The devices
incorporate both over-temperature and over-current
protection.
The TC1054, TC1055 and TC1186 are stable with an
output capacitor of only 1 µF and have a maximum
output current of 50 mA, 100 mA and 150 mA,
respectively. For higher output current regulators,
please refer to the TC1173 (I
(DS21632).
