TPS735285DRVR Equivalent & Substitute Parts

Part Overview

The TPS735285DRVR is a linear voltage regulator IC from Texas Instruments designed for positive fixed output applications. This device delivers 500mA output current at a fixed 2.85V output voltage with a maximum dropout voltage of 0.5V at full load. The regulator integrates protection features including over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO) protection, making it suitable for low-power supply applications requiring stable voltage regulation in compact form factors.

The TPS735285DRVR maintains Active product status and is RoHS3 compliant with MSL Level 1 rating. Identifying equivalent substitute parts is necessary for supply chain continuity, inventory optimization, and design flexibility when the primary part becomes unavailable or when alternative packaging or lead times are required.

Engineering Selection Recommendations

The TPS735285DRVT is a direct parametric equivalent to the TPS735285DRVR. Both parts are manufactured by Texas Instruments, maintain Active product status, and carry identical electrical specifications and protection feature sets. Both devices are RoHS3 compliant with MSL Level 1 rating and REACH Unaffected status, ensuring regulatory compliance across global markets.

Selection between these parts should be based on availability, lead time, and packaging requirements. The difference between DRVR and DRVT designations relates to packaging tape configuration (Tape & Reel specifications), not electrical performance. Both parts are suitable for direct substitution in applications requiring a 2.85V, 500mA linear regulator with the specified protection features and operating temperature range.
