GENERAL DESCRIPTION
The TC1070 is an adjustable LDO designed to super-
cede a variety of older (bipolar) voltage regulators. De-
signed specifically for battery-operated systems, the
TC1070’s CMOS construction eliminates wasted ground
current, significantly extending battery life. Total supply
current is typically 50
μ
A at full load (20 to 60 times lower
than in bipolar regulators).
TC1070 key features include ultra low noise operation
very low dropout voltage (typically 100mV at full load) and
internal feed-forward compensation for fast response to
step changes in load. Supply current is reduced to less than
1
μ
A when the shutdown input is low. The TC1070 incorpo-
rates both over-temperature and over-current protection.
Output voltage is programmed with a simple resistor divider
from V
OUT
to ADJ.
The TC1070 is stable with an output capacitor of only
1
μ
F and has a maximum output current of 50mA. For higher
output versions, please see the TC1107, TC1108
(I
OUT
= 300mA) data sheets.
