TPS71401DCKT

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

The TPS71401DCKT is a single-output adjustable low-dropout (LDO) voltage regulator manufactured by Texas Instruments. It operates within an input voltage range of 2.5 V to 10 V and provides an output current capability of 80 mA. The device features an ultra-low quiescent current of 3.2 µA, making it suitable for battery-powered applications. The adjustable output voltage ranges from 1.2 V to 8.8 V. It exhibits a maximum dropout voltage of 1.3 V at full load and maintains line regulation of 5 mV and load regulation of 30 mV. The component is housed in an SC-70-5 surface-mount package and supports operation across a temperature range of -40°C to +125°C.

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

Verify the specific suffix 'DCKT' against the manufacturer's official datasheet to confirm the reel quantity and tape-and-reel specifications. Ensure the ordering part number matches the required package variant and temperature grade. Cross-reference with the latest Texas Instruments documentation to validate any recent design or packaging changes before finalizing procurement.

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

Select this component when a low-cost, small-footprint LDO with adjustable output is required for currents up to 80 mA. It is appropriate for systems where minimizing standby power consumption is critical. Compare its dropout characteristics and quiescent current against fixed-voltage alternatives if system efficiency dictates a specific output level without external programming.

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

This device belongs to the TPS714 series of low-dropout regulators designed for high-efficiency performance in compact packages. The series emphasizes low static current and wide input voltage ranges, targeting applications such as mobile phones, PDAs, and other handheld instruments where power management and board space are limiting factors.

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

Consult the TPS714 family datasheet for pin-compatible alternatives with different fixed output voltages or slightly varied current ratings. Verify that any substitute maintains the SC-70-5 package dimensions and thermal characteristics to ensure mechanical fit.
