In the event of an overcurrent condition, our LDO regulators are protected by foldback.
The term “foldback” is derived from the shape of the output current (IOUT)-vs-output voltage (VOUT) curve that folds back as shown in Figure 1 during protection operation.
Under a short-circuited load condition, foldback reduces IOUT as VOUT decreases. When VOUT has dropped to zero, it keeps the output current at a limited constant level.
When the overcurrent condition has disappeared, VOUT returns to the normal level automatically.
If an output capacitor or a capacitive load is connected to the output pin, VOUT increases while IOUT is limited by foldback.
