The TC1262 is a precision, fixed output LDO. Unlike
bipolar regulators, the TC1262’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).
Figure 3-1 shows a typical application circuit.

A 1µF (min) capacitor from V
The output capacitor should have an effective series
resistance greater than 0.1Ω and less than 5Ω, and a
resonant frequency above 1MHz. A 1µF capacitor
should be connected from V
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,
response can be improved by increasing the value of
the input and output capacitors and employing passive
filtering techniques.
