DETAILED DESCRIPTION
The TC59 is a low quiescent current, precision fixed
negative output voltage LDO. Unlike bipolar linear
regulators, the TC59 supply current does not increase
proportionally with load current.
3.1
Output Capacitor
A minimum of 1
μ
F tantalum output capacitor is
required. The requirements for the output capacitor are
an equivalent series resistance (esr) greater than 0.1
and less than 5
, with a self-resonant frequency
greater than 1MHz. To improve supply noise rejection
and transient response, larger output capacitors can be
used. Care should be taken when increasing C
OUT
, that
the input impedance is not high enough to cause high
input impedance oscillation.
3.2
Input Capacitor
A 1
μ
F input capacitor is recommended for most
applications when the input impedance is on the order
of 10
. When operating off of a battery input, or there
is a large distance from the input source to the LDO,
larger input capacitance may be required for stability.
When large values of output capacitance are used, the
input capacitance should be increased to prevent high
source impedance oscillations.
