TPS71718DSET

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TPS71718DSET is a single-output low dropout linear regulator from the Texas Instruments TPS717 series. It provides a fixed 1.8 V output with a maximum load current of 150 mA. The device operates within an input voltage range of 2.5 V to 6.5 V and features a typical dropout voltage of 170 mV at full load. Quiescent current is specified at 45 uA, with an input bias current of 50 uA. Line regulation is 125 uV/V and load regulation is 120 uV/mA. Power dissipation is rated at 485 mW. It functions in temperatures from -40 C to +125 C and is housed in a WSON-6 surface-mount package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix DSET corresponds to the WSON-6 package configuration when sourcing. Confirm RoHS compliance status via the manufacturer datasheet prior to integration. Ensure the ordering part number matches the required fixed output voltage variant within the TPS717 family to avoid functional mismatches during assembly.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 1.8 V rail is required with minimal footprint constraints. The WSON-6 package offers a smaller profile compared to larger SOT packages. Consider the 150 mA current limit and 6.5 V maximum input voltage against system requirements. Evaluate thermal management needs based on the 485 mW power dissipation rating under expected load conditions.
