概述

Description

The LT1761ES5-1.2 is a low dropout (LDO) linear voltage regulator designed by Analog Devices. It provides a stable output voltage of 1.2V with a maximum output current of 20mA. The device features a low dropout voltage, typically around 300mV at full load, allowing it to operate efficiently in battery-powered applications. With a low quiescent current of 30µA, it helps extend battery life, making it ideal for portable devices.
The LT1761ES5-1.2 has excellent power supply rejection ratio (PSRR), ensuring minimal output voltage variation due to fluctuations in the input voltage. It also includes built-in short-circuit and thermal protection to enhance reliability.
The LDO comes in a small SOT-23 package, making it suitable for space-constrained applications. It is commonly used in portable electronics, sensors, and low-power microcontroller systems, where low noise and stable voltage are critical.

Package

The LT1761ES5-1.2 is packaged in a 5-lead SOT-23 (SOT-23-5) surface mount package. This compact format is designed for space-constrained applications, providing a convenient solution for voltage reference needs.

Pinout

The LT1761ES5-1.2 is a low-dropout (LDO) linear voltage regulator from Analog Devices. It comes in a 5-lead SOT-23 package. The pin count is 5, and the functions of the pins are as follows:
1. Pin 1 (VIN): This is the input voltage pin where the supply voltage is applied.
2. Pin 2 (GND): This is the ground pin, which serves as the reference point for the input and output voltages.
3. Pin 3 (VOUT): This is the output voltage pin that provides a regulated output voltage of 1.2V.
4. Pin 4 (NC): This pin is not connected (no connection) and should be left floating.
5. Pin 5 (SHDN): This is the shutdown pin, used to enable or disable the regulator. A high signal enables the device, while a low signal puts it in shutdown mode.
The LT1761ES5-1.2 is known for its low dropout voltage and high performance in various applications.
