TLV71128518DDSET

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

The TLV71128518DDSET is a dual-channel low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments. It integrates two independent regulators within a single 6-pin WSON package, providing fixed output voltages of 2.85 V and 1.8 V. Each channel supports a maximum continuous output current of 200 mA with a typical dropout voltage of 150 mV at full load. The device operates from an input voltage range up to 5.5 V and maintains a quiescent current of approximately 30 µA. It features high power supply rejection ratio (PSRR) for noise-sensitive applications and includes comprehensive protection mechanisms such as overcurrent limiting, thermal shutdown, and reverse polarity protection.

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

Verify the complete part number against official Texas Instruments documentation to ensure correct output voltage combinations and package type. Confirm RoHS compliance status and specific ordering suffixes for tape-and-reel or cut-tape options. Cross-reference datasheet revisions to validate pinout configurations and electrical characteristics before integration into design specifications.

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

Select this component when space-constrained designs require two distinct regulated voltages from a single source. The dual-output configuration simplifies board layout compared to using separate single-channel LDOs. Ensure the total system current demand does not exceed the combined capabilities of both channels while maintaining adequate input-to-output voltage differential for regulation.
