概述

Description

The LT1763CDE-3.3#PBF is a low-dropout (LDO) linear voltage regulator designed by Analog Devices, previously known as Linear Technology. It features a fixed output voltage of 3.3V and is capable of delivering a maximum output current of 500mA. This device is known for its low dropout voltage, typically around 300mV at full load, which makes it ideal for applications with low input-output voltage differences.
The LT1763CDE-3.3#PBF has a low quiescent current, typically 30µA, which helps in conserving power, making it suitable for battery-operated devices. Its other features include a low noise output, with an integrated noise bypass capacitor for minimizing output noise, and a fast transient response, ensuring stability across various loads and conditions.
Moreover, this regulator offers excellent line and load regulation, along with several protection features like current limiting and thermal shutdown. It is housed in a thermally enhanced 8-lead plastic DFN package, ensuring efficient heat dissipation. The "#PBF" suffix indicates that the product is lead-free and RoHS compliant, aligning with environmental standards.
