This single-output positive LDO includes an enable pin for sequenced power-up or shutdown. Protection features — over-current, over-temperature, and undervoltage lockout (UVLO) — are built in, so no external supervisor is needed for basic rail monitoring.
For BOM freeze or PCN-sensitive projects, this part carries no imminent lifecycle risk.
This is a fixed-output variant of the TPS7A10 series. Other fixed-voltage options (e.g., 0.8V, 1.8V, 3.3V) share the same 6-WSON footprint and pinout, so a voltage change within the family is a direct drop-in if the load and input rail permit.
PSRR is 60dB at 1kHz and 35dB at 1.5MHz. It provides strong low-frequency ripple rejection but less attenuation at switching-regulator frequencies — plan input filtering if the supply has high-frequency ripple above 1MHz.
