Descripción general

Description

The TL1963A-33DCYR is a low-dropout (LDO) linear voltage regulator designed to provide a stable 3.3V output from a higher voltage input, with a maximum output current of 1.5A. Manufactured by Texas Instruments, this device is part of the TL1963 series known for its low dropout voltage, typically around 340mV at full load, and low noise performance, making it suitable for sensitive analog and RF applications. The regulator features a wide input voltage range, high accuracy, and excellent line and load regulation. It includes an enable pin for on/off control and has built-in protection features such as overcurrent and overtemperature shutdown. The TL1963A-33DCYR is typically packaged in a TO-263 surface-mount form factor, which allows for efficient heat dissipation. This regulator is commonly used in applications that require a reliable and efficient power supply, such as communication equipment, industrial systems, and consumer electronics.

Features

The TL1963A-33DCYR is a low-dropout (LDO) voltage regulator designed by Texas Instruments. This component provides a regulated output voltage of 3.3V with a maximum output current of 1.5A. Key features include:
1. Low Dropout Voltage: It offers a dropout voltage of approximately 340 mV at full load, enhancing efficiency.

2. High Accuracy: The regulator offers an output voltage accuracy of ±2%, ensuring precise voltage regulation for sensitive applications.
3. Thermal Protection: It includes thermal shutdown and current limit protection features to safeguard against overheating and excessive current flow.
4. Low Noise: The device is designed to produce low output noise, making it suitable for sensitive analog applications.
5. Adjustable Output: Although the specific model is fixed at 3.3V, the series allows for adjustable outputs using a resistor divider for other models.
6. Stability: It is stable with a low ESR (Equivalent Series Resistance) output capacitor, which helps maintain performance across various conditions.
7. Package: The TL1963A-33DCYR comes in a TO-263 (D²PAK) surface-mount package, facilitating compact PCB designs.
These features make it suitable for applications requiring efficient, low-noise, and reliable voltage regulation.

Package

The TL1963A-33DCYR is a low-dropout (LDO) voltage regulator provided by Texas Instruments. It comes in a TO-263 package, which is a surface-mount package type known for its ability to handle higher power levels.

Pinout

The TL1963A-33DCYR is a low-dropout (LDO) voltage regulator from Texas Instruments. It typically comes in a surface-mount SOT-223 package, which has a pin count of 3. The main functions of these pins are:
