Description:
The TC1070, TC1071 and TC1187 devices are
adjustable LDOs designed to supersede a variety of
older (bipolar) voltage regulators. Total supply current
is typically 50 µA at full load (20 to 60 times lower than
in bipolar regulators).
The devices’ key features include ultra low-noise
operation, very low dropout voltage – typically 85 mV
(TC1070), 180 mV (TC1071) and 270 mV (TC1187) at
full load and fast response to step changes in load.
Supply current is reduced to 0.5 µA (maximum) when
the shutdown input is low. The devices incorporate both
overtemperature and overcurrent protection. Output
voltage is programmed with a simple resistor divider
from V
The TC1070, TC1071 and TC1187 devices 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 versions
please see the TC1174 (I
(DS21363).
