TPS72718DSET

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

The TPS72718DSET is a fixed-output low-dropout (LDO) voltage regulator from the Texas Instruments TPS727 series. It provides a fixed 1.8 V output with a maximum continuous output current of 250 mA. The device operates within an input voltage range of 2 V to 5.5 V and maintains regulation with a typical dropout voltage of 130 mV at full load, reaching a maximum of 200 mV. Quiescent current is specified at 7.9 uA, with a maximum operating supply current of 9 uA. It features excellent line regulation of 8 uV and load regulation of 20 uV/mA. The component is housed in a WSON-6 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C.

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

Verify the specific suffix 'DSET' corresponds to the WSON-6 package and tape-and-reel shipping configuration as listed in the official datasheet. Confirm RoHS compliance status through the manufacturer's documentation before procurement. Ensure the ordering part number matches the required 1.8 V fixed output variant to avoid functional mismatches.

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

Select this component when a fixed 1.8 V rail is required with minimal static power consumption. The WSON-6 package offers a compact footprint for space-constrained designs. Verify that the input voltage source remains within the 2 V to 5.5 V operational window under all conditions to ensure stable regulation and prevent dropout or overvoltage stress.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This device belongs to the TPS727 family of ultralow IQ LDO regulators designed for noise-sensitive applications. The family shares common architectural features such as fast transient response and high PSRR, differentiated primarily by fixed output voltage options and packaging variants. The TPS72718 specifically targets the 1.8 V generation requirement common in modern digital logic and analog front-ends.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Consult the official TPS727 family datasheet for direct pin-compatible alternatives with different fixed output voltages, such as the TPS72715DSET for 1.5 V output. Ensure any substitute maintains the same WSON-6 package and electrical specifications regarding quiescent current and dropout voltage.
