TPS71928-28DRVTG4

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

The TPS71928-28DRVTG4 is a dual low-dropout (LDO) linear regulator from the Texas Instruments TPS719xx family. It provides two independent 200mA output channels with fixed nominal voltages of 2.8V for both LDO1 and LDO2. The device operates within an input voltage range of 2.7V to 6.5V and delivers a typical dropout voltage of 230mV at full load. Key electrical characteristics include a total quiescent current of 90μA, an output noise of 70μVRMS, and a power-supply rejection ratio (PSRR) of 65dB at 1kHz. It features fast start-up time of 160μs and includes active output pulldown circuitry.

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

Verify the specific ordering suffix 'TG4' against the manufacturer's official documentation to confirm lead-free status and RoHS compliance details. Ensure the package designation matches the required DRV or YZC form factor for your PCB layout. Confirm availability status as production data may vary by region.

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

Select this component when dual isolated rails are needed in a compact space. The TPS719xx series is suitable for designs requiring active load discharge capabilities not present in the TPS718xx variant. Consider the 2mm x 2mm SON-6 package for optimal thermal performance in portable electronics.

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

This part belongs to the TPS718xx/TPS719xx family of dual LDO regulators designed for portable applications. These devices utilize an advanced BiCMOS fabrication process and feature innovative factory EEPROM programming for precise voltage settings. They are optimized for mobile handsets and WLAN systems where low noise and high PSRR are critical.

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

The TPS71828-28DRVTG4 is a functional substitute lacking the active pulldown feature. Verify pin compatibility and ensure the absence of pulldown requirements before substitution.
