LT1964EDD#TRPBF +BOM

200mA, Low Noise, Low Dropout Negative Micropower Regulator

LT1964EDD#TRPBF General Description

For applications demanding a low dropout voltage and accurate output voltage regulation, the LT1964EDD#TRPBF from Analog Devices is the ultimate choice. With a maximum input voltage of 20V and a fixed output voltage of 5V, this LDO linear regulator can deliver up to 1.5A of output current, making it suitable for a wide array of industrial, automotive, and consumer electronics applications. Its fast transient response and low quiescent current ensure efficient operation, while the built-in thermal shutdown protection and overcurrent/overtemperature protection circuits guarantee the device's safety and reliability. Moreover, its compact 10-pin DFN package allows for easy integration into space-constrained PCB designs, and its wide operating temperature range makes it suitable for use in harsh environments
