Application Information
Figure 3
A typical application of the TLE 7469 is shown in
loop from oscillating a ceramic capacitor of
Q1 and Q2. In contrast to most low drop voltage regulators the TLE 7469 only needs
moderate capacitance at the outputs and tolerates ceramic capacitors to keep the
stability. This offers more design flexibility to the circuit designer enabling the IC also to
operate without tantalum capacitors.
Additional a buffer capacitor C
suppress influences from load surges to the voltage levels. This one can either be an
aluminum electrolytic capacitor or a tantalum capacitor following the application
requirements.
A general recommendation is to keep the drop over the equivalent serial resistor (ESR)
together with the discharge of the blocking capacitor below the Reset Headroom (e.g.
min. 130mV for the 2.6V Output).
