SLVSEW4 April 2019 TPS650002-Q1
The two linear dropout regulators (LDOs) in the TPS650002-Q1 are designed to provide flexibility in system design. Each LDO has a separate voltage input and enable signal. The input can be tied to the output of the step-down converter or the output of another voltage source. Each LDO output discharges to ground automatically when EN_LDOx goes low.
The LDOs are general-purpose devices that can handle inputs from 6 V down to 1.6 V. Figure 19 shows the necessary connections for LDO1. The same architecture applies to LDO2.
