Description

The LT1761ES5-3.3#TRPBF is a low-dropout (LDO) linear voltage regulator from Analog Devices. This specific model provides a fixed output voltage of 3.3V. It is designed for applications requiring efficient voltage regulation with minimal power loss, such as battery-powered devices. The regulator operates with an input voltage range of up to 20V, making it versatile for various applications.
Key features include a low quiescent current of around 20µA, ensuring minimal battery drain when in standby mode, and a very low dropout voltage of approximately 300mV at full load, which is useful for maximizing efficiency when the input voltage is close to the output voltage. The LT1761ES5-3.3#TRPBF also includes features like internal current limiting, thermal shutdown, and reverse-battery protection, enhancing the safety and reliability of the device.
The package type is SOT-23-5, which is compact and suitable for space-constrained applications. This LDO is commonly used in portable electronics, handheld instruments, and applications that require low noise and precision voltage regulation.

Package

The LT1761ES5-3.3#TRPBF is a low-dropout (LDO) linear voltage regulator in a SOT-23-5 package.

Pinout

The LT1761ES5-3.3#TRPBF is a low-dropout (LDO) linear voltage regulator from Analog Devices designed to provide a fixed output voltage of 3.3V. It comes in a 5-lead SOT-23 package, meaning it has a pin count of five. The primary function of this device is to regulate the output voltage to 3.3V while supplying up to 100 mA of output current.
Here is a brief overview of the pin functions:
1. Input (Pin 1): Connects to the input voltage source, which should be higher than the desired 3.3V output.
2. Ground (Pin 2): The ground reference for the regulator.
3. Output (Pin 3): Provides the regulated 3.3V output.
4. Bypass (Pin 4): Used to connect an optional capacitor to reduce output noise.
5. Shutdown (Pin 5): Used to enable or disable the regulator; pulling this pin low puts the regulator in shutdown mode.
This voltage regulator is commonly used in battery-powered applications where low noise and high efficiency are important.
