PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 2-1.
TABLE 2-1:
PIN FUNCTION TABLE
3.0
DETAILED DESCRIPTION
The TC56 is a precision, fixed output LDO. Unlike
bipolar regulations, the TC56 supply current does not
increase with load current.
3.1
Output Capacitor
A 10
μ
F tantalum capacitor from V
OUT
to ground is
recommended. The output capacitor should have an
effective series resistance greater than 0.1
and less
than 5.0
, and a resonant frequency above 1MHz. It is
recommended that a 4.7
μ
F capacitor be connected
from V
IN
to GND. 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.
3.2
Shutdown Input
The TC56 enters a low power shutdown mode when
the shutdown control input (SHDN) is low. During
shutdown, the regulator is disabled and supply current
is reduced to 0.1
μ
A (max). Normal operation is
restored when SHDN is driven high. If not required, the
SHDN input can be tied to V
IN
.
