TC2014/2015/2185
4.0
The TC2014, TC2015 and TC2185 are precision fixed-
output voltage regulators (if an adjustable version is
needed, see the TC1070, TC1071 and TC1187
(DS21353) data sheet). Unlike bipolar regulators, the
TC2014, TC2015 and TC2185 supply current does not
increase with load current. In addition, the LDO’s out-
put voltage is stable using 1 µF of ceramic or tantalum
capacitance over the entire specified input voltage
range and output current range.
Figure 4-1 shows a typical application circuit. The reg-
ulator is enabled anytime the shutdown input (SHDN)
is at or above V
SHDN is at or below V
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, the
supply current decreases to 0.05 µA (typical) and V
falls to zero volts.

4.1
A 0.01 µF ceramic 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 the result is a longer time period to rated
output voltage when power is initially applied.

Resistance (ESR) of 0.01Ω to 5Ω for V

minum electrolytic capacitors can be used. When using
ceramic capacitors, X5R and X7R dielectric material
are recommended due to their stable tolerance over
temperature. However, other dielectrics can be used as
long as the minimum output capacitance is maintained.
4.3
A 1 µF capacitor should be connected from V
if there is more than 10 inches of wire between the reg-
ulator and this AC filter capacitor, or if a battery is used
as the power source. Aluminum electrolytic or tantalum
capacitors can be used (since many aluminum electro-
lytic capacitors freeze at approximately -30°C, solid
tantalum 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.
