Description
Introduction to TPS76618DR:
The TPS76618DR is a fixed-output low-dropout regulator (LDO) from Texas Instruments, part of the TPS766 family. It provides a stable 1.8 V rail from a higher input voltage and is intended for powering 1.8 V digital logic in portable and embedded designs.
Key features (high level):
- Fixed 1.8 V output
- Low quiescent current (long battery life)
- Low dropout for operation with modest headroom
- Built-in protection: current limit and thermal shutdown
- Enable (EN) pin to disable the regulator for power saving
- Compact packaging suitable for compact PCB designs
Typical applications:
- Microcontrollers, memory, and sensors that run at 1.8 V
- Wearables, IoT devices, and other battery-powered electronics
Note: For exact electrical specs, recommended operating conditions, and packaging options, see the TI TPS76618DR datasheet and product page.
