TPS77801DG4

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

The TPS77801DG4 is a 750-mA low-dropout voltage regulator with an active-high power-good output, manufactured by Texas Instruments. It operates within an input voltage range of 2.7 V to 10 V and provides an adjustable output voltage from 1.2 V to 5.5 V. The device features ultralow quiescent current of 85 µA typical and supports fast transient response when used with a 10-µF low ESR capacitor. It includes thermal shutdown protection and is housed in an 8-pin SOIC package.

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

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the SOIC package dimensions match your PCB footprint requirements. Ensure the adjustable output configuration aligns with your external resistor divider design constraints before finalizing procurement.

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

Select this component when an adjustable output voltage between 1.2 V and 5.5 V is required alongside a power-good monitoring function. It is suitable for applications demanding high efficiency due to its low dropout characteristics and minimal ground current consumption across the full load range.

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

This part belongs to the TPS778xx family of low-dropout regulators designed for fast transient response. It shares architectural similarities with the TPS777xx series but distinguishes itself through the inclusion of a power-good output rather than a reset signal. The DG4 designation specifies the 8-pin SOIC package variant with environmental compliance.

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

TPS77801D serves as a direct functional equivalent without the G4 suffix.
