LDO Product

Description

As a power management chip between a power supply and an electronic device, a low-dropout linear regulator (LDO) is responsible for the functions of converting, distributing, detecting, and stabilizing and reducing noise.

Low Power Consumption
Low Dropout Voltage
Low Temperature Coefficient
High Input Voltage 
High Voltage Accuracy
