The LP38690SDX-ADJ/NOPB from Texas Instruments is an adjustable low dropout linear regulator delivering up to 1A. With a 1.25V reference and 55µA quiescent current, it offers flexibility and efficiency for a wide range of applications. The 6-WSON package is ideal for compact designs.
- High Current Capacity: 1A output supports power-hungry loads.
- Adjustable Output: Set voltage from 1.25V up with external resistors.
- Low Power Loss: 55µA quiescent current improves efficiency.
- Good Ripple Rejection: 55dB at 120Hz for stable output.
High-Current Adjustable Power Rails
The 1A output capability and adjustable voltage make it suitable for powering FPGAs, DSPs, and microprocessors that require a custom core voltage.
Battery-Powered Industrial Equipment
The low 55µA quiescent current extends battery life in portable industrial tools and field instruments.
Post-Regulation for Switching Converters
Use after a buck converter to provide a clean, low-noise adjustable rail for analog and mixed-signal circuits.
Automotive Infotainment Systems
With 55dB PSRR at 120Hz, it effectively rejects rectified AC ripple in vehicle power systems.
Lab Power Supplies and Bench Equipment
The adjustable output allows precise voltage setting for test fixtures and prototyping.
