概述

Description

The LP2980AIM5-3.3 is a low-dropout (LDO) linear voltage regulator from Texas Instruments. It is designed to provide a stable 3.3V output with a maximum output current of 50mA. The device operates with an input voltage range from 2.1V to 16V, making it suitable for various applications, including battery-powered devices and systems requiring a stable 3.3V power supply.
Key features of the LP2980AIM5-3.3 include a low dropout voltage of typically 120mV at 50mA, high power supply rejection ratio (PSRR), low quiescent current, and excellent load and line regulation. It also offers short-circuit protection and thermal shutdown for enhanced reliability.
Packaged in a small SOT-23-5 form factor, the LP2980AIM5-3.3 is suitable for compact circuit designs. Its high-performance characteristics and ease of use make it ideal for powering microcontrollers, sensors, and other digital or analog components that require a regulated 3.3V supply.

Features

The LP2980AIM5-3.3 is a low-dropout (LDO) voltage regulator designed by Texas Instruments. It provides a fixed output voltage of 3.3V with a maximum output current of 50 mA. Key features include:
1. Low Dropout Voltage: The LDO design ensures a dropout voltage typically around 50 mV at light loads, which is beneficial for battery-operated devices.
2. Low Quiescent Current: Consumes minimal current during operation, enhancing battery life in portable applications.
3. High Accuracy: Offers an output voltage accuracy of ±0.5% at room temperature, ensuring reliable performance.
4. Thermal Protection: Built-in thermal shutdown prevents damage due to overheating by disabling the output when the die temperature exceeds safe levels.
5. Current Limiting: Provides protection by limiting the output current to safeguard against short-circuit conditions.
6. Small Package: Available in a small SOT-23-5 package, making it suitable for space-constrained applications.
7. Stable with Low ESR Capacitors: Compatible with low equivalent series resistance (ESR) capacitors, enabling design flexibility.
These features make the LP2980AIM5-3.3 ideal for applications requiring efficient voltage regulation in a compact form factor.

Package

The LP2980AIM5-3.3 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. It is packaged in a SOT-23-5 package, which is a small outline transistor package with 5 leads, suitable for surface-mount technology (SMT) applications.

Pinout

The LP2980AIM5-3.3 is a low-dropout (LDO) voltage regulator with a fixed output voltage of 3.3V. It comes in a 5-pin SOT-23 package. Here is a brief overview of its pin functions:
1. Pin 1 (GND): Ground pin serves as the reference point for the regulator.
2. Pin 2 (VOUT): Output pin where the regulated 3.3V output voltage is provided.
3. Pin 3 (N/C): No connection; not internally connected, often used for mechanical stability or thermal dissipation.
4. Pin 4 (VIN): Input pin where the input voltage is supplied. This voltage should be higher than the desired output voltage to ensure proper regulation.
5. Pin 5 (Shutdown, SHDN): This pin is used to enable or disable the regulator. Connecting this pin to ground puts the device in shutdown mode, significantly reducing its quiescent current.
The LP2980AIM5-3.3 is designed for applications requiring a stable 3.3V output with minimal input-output voltage differential, suitable for portable and battery-powered devices.
