TPS71727DCKT

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

The TPS71727DCKT is a single-output low-dropout linear voltage regulator from the Texas Instruments TPS717 series. It provides a fixed 2.7V output with a maximum load current of 150mA. The device operates within an input voltage range of 2.5V to 6.5V and features a typical dropout voltage of 170mV at full load, with a maximum of 300mV. Quiescent current is specified at 45µA. It includes integrated protection mechanisms such as overcurrent limiting, thermal shutdown, reverse polarity protection, and under-voltage lockout. The component is housed in a compact SC-70-5 surface-mount package.

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

Verify the specific suffix 'DCKT' corresponds to the cut-tape packaging format rather than the reel variant 'DCKR'. Confirm RoHS compliance status and ensure the operating temperature range meets environmental requirements. Cross-reference the manufacturer part number with official datasheets to validate pinout and electrical characteristics before integration.

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

Select this component when a fixed 2.7V rail is required with minimal footprint. The SC-70-5 package offers a small form factor compared to larger SOT or SOIC options. Ensure input voltage remains above the minimum threshold while accounting for dropout voltage under maximum load conditions to maintain regulation stability.

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