Description

The LT1763CS8-1.8 is a low-dropout (LDO) linear voltage regulator designed by Analog Devices, formerly Linear Technology. It provides a fixed output voltage of 1.8V while handling input voltages ranging from 1.8V to 20V. This regulator is capable of supplying up to 500mA of output current. It is known for its low quiescent current of approximately 30µA, making it efficient for battery-powered applications.
Key features of the LT1763CS8-1.8 include low dropout voltage (typically 300mV at full load), fast transient response, and low output noise of 20µVRMS, facilitated by an external 10nF bypass capacitor. The device also offers excellent line and load regulation. It is equipped with current limiting and thermal shutdown protection to enhance reliability.
Housed in an 8-lead SOIC (Small Outline Integrated Circuit) package, the LT1763CS8-1.8 is suitable for applications requiring stable voltage regulation, such as hand-held devices, wireless communication systems, and precision analog circuits. Its small form factor and robust performance make it a versatile choice for various electronic designs.
