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

µF tantalum output capacitor is

required. The requirements for the output capacitor are

an equivalent series resistance (esr) greater than 0.1

Ω

and less than 5

Ω, 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 COUT, that

the input impedance is not high enough to cause high

input impedance oscillation.

3.2

Input Capacitor

A1

µF input capacitor is recommended for most

applications when the input impedance is on the order

of 10

Ω. 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.
