DETAILED DESCRIPTION
3.2
Input Capacitor
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.
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.
3.1
Output Capacitor
When large values of output capacitance are used, the
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.
2002 Microchip Technology Inc.
input capacitance should be increased to prevent high
source impedance oscillations.
