Overview

Description

The LT1763IS8 is a low-dropout (LDO) linear voltage regulator designed for applications requiring efficient voltage regulation with minimal power loss. It is manufactured by Analog Devices, previously Linear Technology. This component typically supports an input voltage range and provides a regulated output voltage with low dropout, making it suitable for battery-powered devices and applications with tight voltage regulation requirements.
Key features of the LT1763IS8 include a low quiescent current, which helps in maximizing battery life, and a low output voltage noise, ensuring stable operation for sensitive circuits. It also offers thermal shutdown and current limiting protection, enhancing reliability and safety. The device is available in an 8-lead SOIC package, which allows for easy integration into various circuit designs.
The LT1763IS8 is ideal for applications such as portable instruments, handheld devices, and post-regulation of switching power supplies where low noise and low dropout are critical for performance.

Equivalent

The LT1763IS8 is a low-noise, low-dropout (LDO) linear regulator. Equivalent products include the Texas Instruments LP2985 series, the Microchip Technology MCP1700 series, and the ON Semiconductor NCP series, like the NCP1117. Each of these offers similar features such as low dropout voltage, low noise, and stable operation with low output capacitance. When selecting an equivalent, ensure that the voltage, current, and package specifications meet your application's requirements.

Features

The LT1763IS8 is a low dropout (LDO) linear voltage regulator designed by Linear Technology, now part of Analog Devices. Key features of the LT1763IS8 include:
1. Low Dropout Voltage: It offers a low dropout voltage of 300mV at 500mA load current.
2. Output Current: It can deliver up to 500mA of output current.
3. Quiescent Current: The device features very low quiescent current, typically 30µA, which is efficient for battery-powered applications.
4. Input Voltage Range: The regulator operates over a wide input voltage range, generally from 1.8V to 20V.
5. Output Voltage: It provides fixed output voltages, typically available in 1.5V, 1.8V, 2.5V, 3.3V, and 5V options.
6. Thermal Protection: It includes thermal shutdown protection to prevent overheating.

Pinout

The LT1763IS8 is a low dropout (LDO) linear voltage regulator. It typically comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. Here is a brief overview of its pin configuration and functions:
1. Pin 1 (SHDN): Shutdown pin. A high input to this pin enables the regulator, while a low input disables it.
2. Pin 2 (GND): Ground pin. It is the reference point for all voltages in the IC.
3. Pin 3 (OUT): Regulated output voltage pin. It provides the output voltage to the load.
4. Pin 4 (OUT): Another regulated output voltage pin, often internally connected to Pin 3.
5. Pin 5 (SENSE): Sense pin. It allows remote sensing of the output voltage for improved regulation.
6. Pin 6 (FB): Feedback pin. Used to set the output voltage by connecting to an external resistor divider.
7. Pin 7 (IN): Input voltage pin. This is where the unregulated input voltage is supplied.
8. Pin 8 (BYPASS): Bypass pin. It allows for connecting a capacitor to reduce output noise.
The LT1763 is known for its low noise and low dropout voltage characteristics, making it suitable for battery-powered applications.
