Applications
The TPS79618DCQG4 is widely used in portable consumer electronics, wireless IoT modules, and battery-powered devices where a stable 1.8V supply is required for microcontrollers, FPGAs, and memory interfaces. Its low dropout voltage makes it ideal for applications powered directly from Li-Ion batteries or low-voltage DC-DC converter outputs. It is also well-suited for post-regulation in RF transceivers, ADC reference supplies, and noise-sensitive analog front-end circuits where clean power delivery is critical.

Frequently Asked Questions
What is the dropout voltage of the TPS79618DCQG4?
The TPS79618DCQG4 has a typical dropout voltage of 300mV and a maximum of 1V at a 1A load current. This low dropout characteristic allows it to regulate a 1.8V output from an input as low as 2.7V, making it highly efficient for battery-powered applications.
What are the input voltage limits for the TPS79618DCQG4?
The TPS79618DCQG4 supports an input voltage range of 2.7V to 5.5V, with an absolute maximum of 6V. This range is compatible with common supply rails including single-cell Li-Ion batteries (3.0V–4.2V), 3.3V logic supplies, and 5V USB power.
What package does the TPS79618DCQG4 use and what are typical applications?
The TPS79618DCQG4 comes in a 6-pin SOT-223 package with an exposed thermal pad for better heat dissipation. It is typically used in portable devices, IoT sensors, RF modules, and embedded systems requiring a clean, regulated 1.8V supply for processors, memory, and analog circuits.
Is the TPS79618DCQG4 RoHS compliant?
The TPS79618DCQG4 is REACH compliant. However, its Pb-free code is listed as No, indicating it may contain lead. Designers should verify the latest compliance documentation from Texas Instruments before use in RoHS-restricted applications.
