概述

Description

The TPS77033DBVR is a low-dropout (LDO) voltage regulator from Texas Instruments, designed to provide a stable output voltage of 3.3 volts. It is part of the TPS770xx series, which is known for its low power consumption and high efficiency. This device is ideal for battery-powered applications as it features an ultra-low quiescent current of approximately 92 µA, which helps extend battery life. The regulator can supply up to 50 mA of output current and operates with an input voltage range from 2.7 V to 10 V.
The TPS77033DBVR comes in a small SOT-23-5 package, making it suitable for compact applications. It also includes features like thermal shutdown and current limit protection, ensuring safety and reliability in various operating conditions. With a dropout voltage of typically 49 mV at 50 mA, this LDO is efficient for applications requiring low dropout performance. Additionally, its fast transient response and low output noise make it suitable for sensitive circuits. The device is commonly used in portable devices, communication equipment, and other electronics requiring reliable voltage regulation.

Package

The TPS77033DBVR is a low-dropout (LDO) voltage regulator produced by Texas Instruments. The package type is SOT-23, specifically a 5-pin SOT-23-5, which is a small-outline transistor package designed for surface-mount applications.

Pinout

The TPS77033DBVR is a low-dropout (LDO) voltage regulator from Texas Instruments. It is designed to provide a stable 3.3V output voltage. The device is housed in a 5-pin SOT-23 (DBV) package. Here is a concise description of its pin functions:
1. Pin 1 (IN): This is the input voltage pin where the unregulated voltage is applied.
2. Pin 2 (GND): This is the ground pin and serves as a reference point for the circuit.
3. Pin 3 (EN): This is the enable pin. The LDO is operational when this pin is held high and goes into shutdown mode when held low.
4. Pin 4 (NC): This pin is internally not connected.
5. Pin 5 (OUT): This is the output pin, where the regulated 3.3V is provided.
The TPS77033 is optimized for low power applications, offering low dropout voltage and low quiescent current, making it ideal for battery-operated devices.
