概述
Description
The LT1965IDD-3.3#PBF is a low-dropout (LDO) linear voltage regulator designed by Analog Devices. It provides a stable 3.3V output voltage from a higher voltage input with a maximum output current of 1.1A. The "IDD" denotes the device's package type, which is a 8-lead (3mm × 3mm) DFN, and "PBF" indicates it is lead-free and RoHS compliant.
Key features include a low dropout voltage of 300mV at full load, high ripple rejection, and low quiescent current, making it suitable for applications requiring efficient power management like battery-powered devices. The LT1965 offers protection features such as current limiting, thermal shutdown, and reverse battery protection. It also includes a shutdown mode for conserving power.
The device is ideal for powering low-voltage microprocessors, DSPs, and other digital logic circuits. Its small form factor and high performance make it a versatile choice for space-constrained applications.
