LDO2 automatic voltage tracking and de-tracking of LDO1 or of an external LDO

voltage represents an accurate solution for automotive off-board sensors and small

current off-board modules, where the power supply runs through a long cable from

the main board.

Under this condition, the long cable might be damaged, causing short-to-ground,

short-to-battery or other fault events. In these cases, the system needs to implement

a mechanism to protect on-board components from being damaged. Meanwhile, it is

necessary to keep the voltage-tracking tolerance between the off-board sensors

power supply and the MCU/ADC power supply to the lowest level. In this scenario,

the voltage-tracking LDO represents the perfect solution for driving the off-board

loads, offering full protection features and ultra-accurate output tracking voltage.
