General Description
The TC2014, TC2015 and TC2185 are high-accuracy
(typically ±0.4%) CMOS upgrades for bipolar Low
Drop-out Regulators (LDOs), such as the LP2980.
Total supply current is typically 55 µA; 20 to 60 times
lower than in bipolar regulators.
The key features of the device include low noise oper-
ation (plus bypass reference), low dropout voltage
typically 45 mV for the TC2014, 90 mV for the
TC2015, and 140 mV for the TC2185, at full load – and
fast response to step changes in load. Supply current
is reduced to 0.5 µA (max) and V
OUT
falls to zero when
the shutdown input is low. These devices also
incorporate overcurrent
and overtemperature
protection.
The TC2014, TC2015 and TC2185 are stable with an
output capacitor of 1 µF and have maximum output
currents of 50 mA, 100 mA and 150 mA, respectively.
For higher-output
current versions, see the TC1107
(DS21356), TC1108 (DS21357) and TC1173
(DS21362) (I
OUT
= 300 mA) data sheets.
