High-Performance LDO from GigaDevice
High-performance power IC is the cornerstone of all electronic products. GigaDevice is committed to providing customers with various regulated power supply solutions with low noise, low power consumption, high sensitivity and high efficiency, and continues to expand its products.
GD30 series low-dropout linear regulators (LDO):
- Load current up to 3 A
- maximum voltage drop of only 180 mV @ 3A
- very low noise
- fast reaction to load changes
- multiple protection functions
This IC is perfect for powering the most demanding chips and modules. Fast response and high current efficiency make this IC ideal for wi-fi infrastructure, industrial, communication, medical, etc. applications.
