Its 3 µA quiescent current suits always-on or battery-powered designs where the regulator's own draw must stay below the system sleep budget. ## PSRR flat across 1 kHz to 1 MHz PSRR holds at 40 dB from 1 kHz through 1 MHz — a wide-band rejection profile that attenuates switching-regulator ripple and high-frequency noise without requiring a post-filter. For a 200 mVpp ripple at 500 kHz, the output sees roughly 2 mVpp after regulation. ## Dropout and protection at 200 mA Maximum dropout is 308 mV at the full 200 mA load — the input rail needs to stay above 3.008 V to maintain regulation. Over-current, over-temperature, and UVLO protection are integrated, so the part survives output shorts and thermal excursions without external clamp diodes. ## SOT-23-3 with enable pin Packaged in a 3-lead SOT-23-3 (TO-236-3, SC-59 equivalent), the TPS7A0527PDBZR mounts on standard surface-mount pads. An enable control pin lets the system power down the regulator, dropping the load current to near-zero during standby.","metaTitle":"TI TPS7A0527PDBZR LDO Regulator, 2.7V Fixed, 200mA, SOT-23-3","metaDescription":"Texas Instruments TPS7A0527PDBZR LDO, fixed 2.7V output, 200mA, 3µA quiescent current, 40dB PSRR 1kHz-1MHz.
