F to 0.1-
μ
F ceramic bypass capacitor between IN and GND, close to the device, is recommended.
Placing a high-value electrolytic capacitor on the output and input pins is recommended when the output load
is heavy. This precaution reduces power supply transients that may cause ringing on the input. Additionally,
bypassing the output with a 0.01-
μ
F to 0.1-
μ
F ceramic capacitor improves the immunity of the device to
short-circuit transients.
overcurrent
A sense FET checks for overcurrent conditions. Unlike current-sense resistors, sense FETs do not increase the
series resistance of the current path. When an overcurrent condition is detected, the device maintains a
constant output current and reduces the output voltage accordingly. Complete shutdown occurs only if the fault
is present long enough to activate thermal limiting.
