Thermal shutdown is an effective means to prevent die
overheating since the power transistor is the principle heat
source in the IC.

Stability Considerations

regulator: startup delay, load transient response and loop
stability.
availability, 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, but, if the circuit operates at low
temperatures (−25°C to −40°C), both the value and ESR of
