It comes in a 6-WSON (2x2 mm) package with an exposed pad for thermal transfer to the PCB. The part is specified over the full -40°C to 125°C temperature range. ## PSRR — what the 65 dB to 40 dB roll-off means for your rail The PSRR of 65 dB at 100 Hz dropping to 40 dB at 100 kHz tells you how much ripple from a switching pre-regulator this LDO can reject. At 100 kHz you get 40 dB of rejection, which attenuates a 100 mVpp ripple to about 1 mVpp. The 80 µA quiescent current keeps the overhead low for always-on subsystems. ## Protection and control Built-in over-current, over-temperature, and under-voltage lockout (UVLO) protect the load and the regulator. The enable pin lets you sequence the rail on/off with a logic signal, which is useful for power-sequencing in multi-rail designs. ## Lifecycle and compliance The TPS728330185DRVT is listed as Active with ROHS3 compliance.","metaTitle":"TI TPS728330185DRVT LDO Regulator, 200 mA, 3.3V/1.85V","metaDescription":"TI TPS728330185DRVT LDO regulator, fixed dual output 3.3V/1.85V, 200 mA, PSRR 65 dB at 100 Hz, -40 to 125°C, 6-WSON.
