Description

The LT1963EST-2.5#PBF is a low dropout (LDO) linear voltage regulator from Analog Devices, designed to provide a stable output voltage of 2.5V. With a low dropout voltage, it efficiently regulates power even when the input voltage is close to the output voltage. The regulator can supply up to 1.5A of output current, making it suitable for various applications, including powering sensitive analog circuitry and microcontrollers.
Key features include a low output noise level, high power supply rejection ratio (PSRR), and a wide operating temperature range. It also includes protection features like thermal shutdown and current limiting. The LT1963EST-2.5#PBF comes in a compact, thermally enhanced package, which aids in efficient heat dissipation.
Overall, this LDO is ideal for low noise, high performance, and space-constrained applications in consumer electronics, automotive, and industrial systems.

Features

The LT1963EST-2.5#PBF is a low dropout (LDO) voltage regulator designed by Analog Devices. Here are its key features:
1. Output Voltage: Fixed output voltage of 2.5V.
2. Dropout Voltage: Ultra-low dropout voltage of 300mV at 200mA load, ensuring efficient operation.
3. Output Current: Capable of delivering up to 1.5A of output current.
4. Low Noise: Very low output noise (20µVRMS, 10Hz to 100kHz), making it suitable for sensitive applications.
5. Power Supply Rejection Ratio (PSRR): High PSRR (typically 75dB at low frequencies) for improved stability against input voltage fluctuations.
6. Thermal Protection: Integrated thermal shutdown feature to prevent overheating.
7. Operating Temperature Range: Wide range of -40°C to 125°C, suitable for various environmental conditions.
8. Package: Available in a compact 5-lead TSOT-23 and 3-lead SOT-223 packages.
