Quiescent current is 65 µA typical, which keeps the regulator's own draw low in always-on or battery-backed applications. ## PSRR profile and noise-sensitive loads Power supply rejection ratio (PSRR) is 66 dB at 100 Hz, rolling off to 22 dB at 100 kHz — this profile means the regulator attenuates low-frequency ripple (e.g., 100/120 Hz from a rectified mains supply) by a factor of ~2000, but passes higher-frequency switching noise with less rejection. For a noise-sensitive analog rail (e.g., an ADC reference or VCO supply), the PSRR at the switching frequency of the upstream converter determines whether additional post-filtering is needed. ## Package and thermal pad Surface-mount assembly; the tape-and-reel option suits automated pick-and-place lines. ## Protection and control Built-in protection includes over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO) — the UVLO prevents the output from turning on until the input rail is high enough to maintain regulation. An enable pin allows the output to be gated by a logic signal, useful for sequencing multiple rails or shutting down the regulator in sleep modes.","metaTitle":"TPS73515DRBT LDO 1.5V 500mA, 8-SON","metaDescription":"Texas Instruments TPS73515DRBT LDO regulator, 1.5V fixed output, 500mA, PSRR 66dB at 100Hz, -40 to 125°C, 8-VDFN exposed pad.
