Figure 27. Reverse Current Test Results (Typical)
The regulator has thermal shutdown circuitry that protects it from damage caused by overload conditions. The
thermal protection circuitry disables the output when the junction temperature reached approximately 160°C,
allowing the device to cool. When the junction temperature cools to approximately 140°C, the output circuitry is
automatically re-enabled. Continuously running the regulator into thermal shutdown can degrade reliability. The
regulator also provides current limit to protect itself and the load.
An enable pin on the regulator may be used to place the device into an energy-saving shutdown mode. In this
mode, the output is disconnected from the input and the input quiescent current is reduced to 10
A maximum.
For minimum output voltage ripple, the output capacitor (COUT) should be a surface-mount ceramic capacitor.
Tantalum capacitors generally have a higher Effective Series Resistance (ESR) and may contribute to higher
output voltage ripple. Leaded capacitors also increase ripple due to the higher inductance of the package itself.
To achieve the best operation with low input voltage and high load current, the input and flying capacitors (CIN
and CFLY, respectively) should also be surface-mount ceramic types.

Generally, CFLY can be calculated by the following simple equation,
