概述

Description

The LP2950CDT-5.0RKG is a low-dropout (LDO) voltage regulator designed to provide a stable 5.0V output. It is known for its precision, low quiescent current, and high efficiency, making it ideal for battery-powered applications. This regulator can handle input voltages up to 30V and provides a maximum output current of 100mA. It features low dropout voltage, making it efficient in supplying power even when the input voltage is only slightly higher than the output voltage.
Key features include:
- Tight output tolerance over temperature, load, and line variations.
- Low quiescent current, which extends battery life.
- Built-in current and thermal limiting to protect against overcurrent and overheating conditions.
The package for the LP2950CDT-5.0RKG is typically a TO-252 surface-mount package, which aids in efficient heat dissipation. This device is suitable for applications in portable electronics, microcontroller power supplies, and other scenarios where a stable 5V output is necessary.

The LP2950CDT-5.0RKG is a voltage regulator designed for applications requiring a stable and precise output voltage. Key features include:
1. Output Voltage: It provides a fixed output voltage of 5.0V.
2. Low Dropout Voltage: It has a low dropout voltage, typically around 0.1V at light loads, which makes it suitable for battery-operated devices.
3. Low Quiescent Current: The regulator features low quiescent current, enhancing battery life in portable applications.
4. High Accuracy: It offers high output voltage accuracy, typically within ±0.5%.
5. Load Regulation: The device provides excellent load regulation, ensuring stable performance under varying load conditions.
6. Thermal Protection: It includes thermal overload protection to prevent damage due to overheating.
7. Current Limiting: The regulator has built-in current limiting for overcurrent protection.
8. Temperature Range: It operates over a wide temperature range, suitable for various environmental conditions.
The LP2950CDT-5.0RKG is commonly used in applications like microcontroller power supplies, battery-powered equipment, and other electronic devices requiring reliable and efficient voltage regulation.

Package

The LP2950CDT-5.0RKG is packaged in a TO-252 (DPAK) surface-mount package. This package type is commonly used for medium power applications and offers a compact and efficient design for heat dissipation.

Pinout

The LP2950CDT-5.0RKG is a low-dropout voltage regulator with a fixed output voltage of 5.0V. It typically comes in a TO-252 (DPAK) package, which has 3 pins. The pin functions are as follows:
1. Input (IN): This pin is where the unregulated input voltage is supplied. The input voltage must be higher than the desired 5.0V output by a certain amount to allow for proper regulation.
2. Ground (GND): This is the common ground pin for both the input and output voltage.
3. Output (OUT): The regulated 5.0V output voltage is provided at this pin. It is used to power the connected circuit that requires a stable 5.0V supply.
These pins work together to provide a stable output voltage, with the regulator maintaining the output voltage despite variations in the input voltage or load conditions.

Manufacturer

The LP2950CDT-5.0RKG is manufactured by ON Semiconductor, which is now known as onsemi. Onsemi is a leading semiconductor supplier that offers a wide range of products, including power and signal management, logic, discrete, and custom devices. The company focuses on providing energy-efficient solutions for various sectors such as automotive, industrial, cloud power, and IoT.

Application

The LP2950CDT-5.0RKG is a low-dropout voltage regulator commonly used in applications requiring efficient power management and voltage regulation. Its primary application areas include battery-powered devices, microcontroller-based systems, portable electronics, and communication devices.
