The TC1070, TC1071 and TC1187 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
over-temperature and over-current protection. Output
voltage is programmed with a simple resistor divider
from VOUT to ADJ to GND.
The TC1070, TC1071 and TC1187 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 (IOUT = 300 mA) data sheet.
