Description

The LT1963AEST-2.5#TRPBF is a low dropout (LDO) linear voltage regulator manufactured by Analog Devices, designed to provide a stable 2.5V output from a higher input voltage. It is part of the LT1963 series, known for its high performance, low noise, and high accuracy. This specific model can deliver up to 1.5A of output current with a dropout voltage of approximately 340mV at full load, making it suitable for applications requiring efficient power conversion with minimal voltage loss.
The device features fast transient response, low output noise, and a wide input voltage range. It includes internal protection mechanisms like thermal shutdown and current limiting to enhance reliability. The "EST" package denotes the SOT-223 package type, which is compact and suitable for surface mounting. The "#TRPBF" suffix indicates that this part is RoHS compliant ("Pb-Free") and available in tape and reel packaging for automated assembly. Typical applications include powering digital circuits, RF systems, and other electronic modules requiring a stable and precise voltage supply.

Package

The LT1963AEST-2.5#TRPBF is a low dropout linear regulator packaged in a SOT-223.

Pinout

The LT1963AEST-2.5#TRPBF is a low dropout (LDO) linear regulator. It comes in a 5-pin SOT-223 package. The function of each pin is as follows:
1. Input (Pin 1): This pin is connected to the input supply voltage. It requires a voltage level higher than the desired output voltage by the dropout voltage to function correctly.
2. GND (Pin 2): This pin is the ground connection for the regulator.
3. Output (Pin 3): This pin provides the regulated output voltage, which is fixed at 2.5V for this specific variant.
4. ADJ (Pin 4): This is the adjust pin, used in different variants for setting the output voltage. In this fixed version, it might be internally configured and not externally accessible or used.
5. Enable (Pin 5): This pin is used to enable or disable the device. When pulled high, the device is enabled; when low, the device is disabled.
This LDO regulator is designed for applications needing a fixed 2.5V output with low dropout and high current capability.
