Visão Geral
Description
This regulator is equipped with internal protection features including thermal shutdown and current limiting to safeguard against overload conditions. The device is housed in a thermally enhanced package, which aids in heat dissipation. It is suitable for applications in telecommunications, computing, and industrial systems where precise voltage regulation is crucial.
The "TRPBF" suffix indicates that the device is RoHS compliant (lead-free) and comes in tape and reel packaging for automated assembly processes. Its robust design, coupled with low noise and high output accuracy, makes the LT1963AEST-3.3#TRPBF a versatile choice for powering sensitive electronic components.
Equivalent
1. Micrel MIC39100-3.3WT: A 1A LDO with similar voltage output.
2. Texas Instruments TPS73533: A 500mA LDO offering low dropout and noise.
3. ON Semiconductor NCP1117ST33T3G: A 1A LDO regulator with similar thermal characteristics.
Always check the datasheets for compatibility in terms of electrical characteristics and package size.
Features
1. Output Voltage: It provides a fixed output voltage of 3.3V.
2. Low Dropout Voltage: The dropout voltage is typically 340mV at full load, allowing for efficient operation with low input-output voltage differentials.
3. Fast Transient Response: It is optimized for fast transient response to changes in load current.
4. Stability: The design supports stability with low-ESR capacitors, which helps in reducing cost and size.
5. Thermal Protection: It includes thermal shutdown circuitry to prevent overheating.
6. Current Limit: It features internal current limiting to protect against overload conditions.
7. Quiescent Current: The device has a low quiescent current, typically around 1mA, enhancing efficiency in battery-powered applications.
8. Package: The LDO is available in a thermally enhanced SOT-223 package.
9. Applications: Suitable for post-regulation in switching power supplies, battery-powered systems, and high-efficiency linear regulation.
These features make the LT1963AEST-3.3#TRPBF versatile for various electronic applications requiring efficient and stable voltage regulation.
Pinout
1. IN: Input voltage pin where the unregulated input voltage is applied.
2. GND: Ground pin, used for the return path of the device.
3. OUT: Output voltage pin where the regulated 3.3V output is obtained.
4. ADJ/SS: Adjust or Soft-Start pin, typically used for adjusting the output voltage or implementing a soft-start feature. However, in this fixed 3.3V version, it's internally connected and not used for adjusting voltage.
5. NC: No connection pin, which is sometimes present in versions of the package for mechanical stability but not electrically connected.
The LT1963AEST-3.3#TRPBF can deliver up to 1.5A of output current with a low dropout voltage, making it suitable for applications requiring efficient power regulation.
