TC1072/TC1073

The TC1072 and TC1073 are precision fixed output
voltage regulators. (If an adjustable version is desired,
please see the TC1070/TC1071/TC1187 data sheet.)
Unlike bipolar regulators, the TC1072 and TC1073’s
supply current does not increase with load current. In
addition, V

regulator is enabled any time the shutdown input
(SHDN) is at or above V
when SHDN is at or below V
controlled by a CMOS logic gate, or I/O port of a
microcontroller. If the SHDN input is not required, it
should be connected directly to the input supply. While
in shutdown, supply current decreases to 0.05 µA

When operating from sources other than batteries,
supply-noise rejection and transient response can be
improved by increasing the value of the input and
output capacitors and employing passive filtering
techniques.

A 470 pF capacitor connected from the Bypass input to
ground reduces noise present on the internal
reference, which in turn significantly reduces output
noise. If output noise is not a concern, this input may be
left unconnected. Larger capacitor values may be
used, but results in a longer time period to rated output
voltage when power is initially applied.
