Quiescent current is 2.6 µA typical, which keeps the regulator's own draw negligible in battery-powered designs. PSRR measures 64 dB at 1 kHz, rolling off to 35 dB at 1.5 MHz — the attenuation curve matters when the input rail carries switching noise from a DC-DC converter upstream. Below 100 kHz the rejection is strong enough to clean a buck output; above 1 MHz, additional filtering or layout care is needed. ## Package and thermal — board integration note Housed in a 6-WDFN with exposed pad (supplier package 6-WSON, 2x2 mm). The Enable pin allows the regulator to be shut down for power sequencing or low-power sleep modes. ## Protection and operating range Built-in protection includes over-current, over-temperature, and under-voltage lockout (UVLO). Input voltage range is 3.3 V max, output fixed at 0.8 V — this is a low-VIN, low-VOUT LDO suited for post-regulation from a 1.2 V or 1.8 V rail down to 0.8 V core supplies.","metaTitle":"TI TPS7A1108PDRVT LDO, 500mA, 0.8V fixed, 6-WSON","metaDescription":"Active Texas Instruments TPS7A1108PDRVT LDO, 500mA output, 0.14V dropout at full load, 2.6µA Iq, PSRR 64dB~35dB, -40°C~125°C.
