Its headline spec is the PSRR: 65 dB at 100 Hz, rolling to 40 dB at 1 MHz — that means it rejects ripple from a switching pre-regulator across the audio band and into the MHz range, so a sensitive analog front-end sees clean DC. Dropout is 140 mV max at full load — the input rail only needs 5.14 V to keep the output in regulation, which matters when the supply is a 5.5 V bus or a battery near end-of-life. Quiescent current is 15 µA, making it a candidate for always-on or battery-backed rails where the regulator's own draw must stay below the system sleep budget. ## Active production, ROHS3 — no lifecycle surprises The 4-X2SON package (1x1 mm) with exposed pad means the thermal path goes through the PCB copper, not the part body. ## Enable pin, full protection set, industrial temp range A single Enable pin lets a GPIO or supervisor sequence the rail on and off — no external PMOS or load switch needed for the 300 mA rail. Built-in Over Current, Over Temperature, and Under Voltage Lockout (UVLO) protection means the LDO shuts itself down before the load or the package sees damage. The UVLO threshold is set internally; no external resistor divider.","metaTitle":"TPS7A2050PDQNR 300mA LDO, 5V Fixed, Ultra-Low-Noise","metaDescription":"Texas Instruments TPS7A2050PDQNR 300mA LDO, 5V fixed output, 15µA Iq, PSRR 65dB~40dB (100Hz~1MHz), 4-X2SON package.
