or adjustable voltages at currents up to 6.0 A. The regulators
are protected against short circuit, and include thermal
shutdown and safe area protection (SOA) circuitry. The
SOA protection circuitry decreases the maximum available
output current as the input−output differential voltage
increases.

detailed procedure for selecting this capacitor is included in
the Stability Considerations section.
Adjustable Operation

sets the output voltage as shown in Figure 10. The regulator
maintains a fixed 1.25 V (typical) reference between the
output pin and the adjust pin.
current to flow to ground. This current creates a voltage
across R2 that adds to the 1.25 V across R1 and sets the
overall output voltage. The adjust pin current (typically
50 μA) also flows through R2 and adds a small error that
should be taken into account if precise adjustment of V
is necessary.

Stability Considerations

delay, load transient response and loop stability.
size and temperature constraints. A tantalum or aluminum
electrolytic capacitor is best, since a film or ceramic
capacitor with almost zero ESR, can cause instability. The
aluminum electrolytic capacitor is the least expensive
solution. However, when the circuit operates at low
temperatures, both the value and ESR of the capacitor will
vary considerably. The capacitor manufacturers data sheet
provides this information.
