TLV713185PDQNR

Product Overview

The TLV713185PDQNR from Texas Instruments is a fixed-output linear voltage regulator intended for compact surface-mount power management. It provides a single positive 1.85 V output at up to 150 mA from an input voltage up to 5.5 V, with a maximum dropout of 0.7 V at full load. The device includes enable control and protection against overcurrent, overtemperature, reverse polarity, short circuit, and under-voltage lockout. Its 4-XDFN exposed-pad package with a 4-X2SON (1x1) footprint supports dense board layouts, while the specified junction temperature range is -40°C to 125°C.

Key Features

• Fixed positive 1.85 V output with a single regulator channel and 150 mA maximum output current.
• Input voltage capability up to 5.5 V, with 0.7 V maximum dropout at 150 mA.
• 75 µA quiescent current and 70 dB to 55 dB PSRR across 100 Hz to 1 MHz.
• Enable control feature for regulator on/off operation.
• Protection features include overcurrent, overtemperature, reverse polarity, short circuit, and under-voltage lockout.
• Surface-mount 4-XDFN exposed-pad package, 4-X2SON (1x1) package.
• Operating junction temperature range of -40°C to 125°C.

Applications

• Regulating a 1.85 V rail for low-power digital logic or sensor circuitry in compact embedded boards.
• Providing controlled power-up or power-down of a load through the enable feature.
• Supplying small analog or mixed-signal subsystems where current limiting and thermal protection are useful.

Design & Procurement Notes

Design considerations should account for the 5.5 V maximum input, the 1.85 V fixed output, and the 0.7 V dropout at 150 mA when selecting the input supply and estimating headroom. The 75 µA quiescent current and 70 dB to 55 dB PSRR across 100 Hz to 1 MHz are relevant for low-current rails and noise-sensitive loads. The enable feature and protection functions support basic power control and fault handling, while the 4-XDFN exposed-pad package requires attention to soldering, pad layout, and thermal management in space-constrained designs.
