8.2.1 Low-Input, Low-Output (LILO) Voltage Conditions
The TPS7A8400A device uses the ANY-OUT configuration to regulate a 3-A load requiring good PSRR at high frequency with low-noise at 0.9 V using a 1.2-V input voltage and a 5-V bias supply. The schematic for this typical application circuit is provided in Figure 8-21.
