PSRR is 60 dB at 1 kHz, which is decent for cleaning up a switching-regulator ripple feeding a sensitive ADC or op-amp. The protection set — over-current, over-temperature, reverse polarity — covers the common fault cases in an industrial or automotive board without needing external clamp diodes. The reverse-polarity block is a nice catch: if someone back-feeds the input, the regulator doesn't let the magic smoke out. Package is SOT-23-5, surface-mount. ## Sourcing and lifecycle The TPS76338DBVT is listed as Active and ROHS3 Compliant. This part is available through independent distribution and is quoted to order against an RFQ — no minimums, no allocation games. If you are freezing a BOM for a multi-year production run, the active status and wide temperature grade make it a low-risk line item.","metaTitle":"TPS76338DBVT LDO Regulator, 3.8V Fixed Output, 150mA","metaDescription":"Texas Instruments TPS76338DBVT LDO regulator: 3.8V fixed output, 150mA, 60dB PSRR at 1kHz, -40°C to 125°C, SOT-23-5.
