FUNCTIONAL DEVICE OPERATION
SUPPLIES
? Short-circuit protection (SCP) is included on certain LDOs (see the SCP section later in this chapter). Exceeding the SCP
threshold will disable the regulator and generate a system interrupt. The output voltage will not sag below the specified voltage
for the rated current being drawn. For the lower current LDOs without SCP, they are less accessible to the user environment
and essentially self-limiting.
? The power tree of a given application must be scrubbed for critical use cases to ensure consistency and robustness in the
power strategy.
TRANSIENT RESPONSE WAVEFORMS
The transient load and line response are specified with the waveforms as depicted in Figure 25 . Note that the transient load
response refers to the overshoot only, excluding the DC shift itself. The transient line response refers to the sum of both overshoot
and DC shift. This is also valid for the mode transition response.

SHORT-CIRCUIT PROTECTION
The higher current LDOs and those most accessible in product applications include short-circuit detection and protection
(VVIDEO, VAUDIO, VCAM, VSD, VGEN1, VGEN2, and VGEN3). The short-circuit protection (SCP) system includes debounced
fault condition detection, regulator shutdown, and processor interrupt generation, to contain failures and minimize chance of
