TC1264
4.0
The TC1264 is a precision, fixed output LDO. Unlike
bipolar regulators, the TC1264’s supply current does
not increase with load current. In addition, V
remains stable and within regulation over the entire
0mA to I
consideration in RTC and CMOS RAM battery back-up
applications).

The output capacitor should have an effective series

is more than 10 inches of wire between the regulator
and the AC filter capacitor, or if a battery is used as the
power source. Aluminum electrolytic or tantalum
capacitor types can be used. (Since many aluminum
electrolytic capacitors freeze at approximately -30°C,
solid tantalums are recommended for applications
operating below -25°C.) 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.
