Descripción general

Description

The LT1763CDE-5 is a precision low-dropout (LDO) voltage regulator from Analog Devices, designed to provide a stable output voltage of 5V with a maximum output current of 100mA. It features a low dropout voltage of 300mV at full load, making it suitable for battery-powered applications where efficiency is crucial.
Key features include low output noise (typically 30µVRMS), high power supply rejection ratio (PSRR), and a wide input voltage range of 1.8V to 20V. The LT1763CDE-5 incorporates a built-in protection mechanism, such as thermal shutdown and current limiting, ensuring reliability and safety in various operating conditions.
This regulator is available in a compact 3-lead TO-220 package, enabling easy integration into space-constrained designs. Its high performance and efficiency make it ideal for applications in telecommunications, portable devices, and precision analog circuits.

Features

The LT1763CDE-5 is a low-dropout (LDO) voltage regulator from Analog Devices designed to provide a stable output voltage of 5V. Key features include:
1. Low Dropout Voltage: Typically 300mV at 200mA load, allowing for efficient operation in battery-powered applications.
2. High Output Current: Capable of delivering up to 200mA of output current.
3. Low Noise: Features low output noise (typically 20µVrms), making it suitable for sensitive RF and analog applications.
4. Wide Input Voltage Range: Accepts input voltages from 1.7V to 20V, providing flexibility in various applications.
5. Temperature Range: Operates over a temperature range of -40°C to 125°C, ideal for automotive and industrial environments.
6. Built-in Protection: Includes overcurrent and thermal protection to ensure reliability.
7. Small Package Size: Available in a compact 8-lead MSOP or 8-lead PDIP package for space-constrained designs.
These features make the LT1763CDE-5 ideal for portable devices, sensor applications, and any system requiring a stable and low-noise power supply.

Package

The LT1763CDE-5 is packaged in a 5-lead SOT-23 (Small Outline Transistor) package. This compact format is commonly used for low-profile applications, providing efficient thermal performance and space-saving benefits.

Pinout

The LT1763CDE-5 is a low-dropout (LDO) linear voltage regulator from Analog Devices with a pin count of 5.
Here are the pin functions:
1. VIN: Input voltage pin; supplies power to the regulator.
2. GND: Ground pin; serves as the reference point for the output voltage and returns current to the system ground.
3. VOUT: Output voltage pin; delivers the regulated output voltage (5V in this case).
4. NC: No connect; this pin is not internally connected and can be left floating.
5. SHDN: Shutdown pin; when pulled low, it disables the output, reducing power consumption.
This regulator is designed for applications requiring a stable output voltage with low dropout voltage and low noise.
