Description

The LT1764EQ-3.3 is a low dropout (LDO) linear regulator, designed by Analog Devices (formerly Linear Technology). It delivers a fixed output voltage of 3.3V with high efficiency and low noise, making it suitable for powering sensitive electronic components and systems. The device can provide an output current of up to 3A, making it ideal for moderate power applications.
Key features of the LT1764EQ-3.3 include its low dropout voltage of approximately 340mV at full load, which allows for efficient operation in battery-powered devices. It also offers fast transient response and current limiting to protect against overcurrent conditions. The regulator incorporates thermal shutdown to prevent overheating, ensuring safe operation under various conditions.
The LT1764EQ-3.3 is housed in a thermally enhanced 5-pin TO-220 package, facilitating effective heat dissipation. Its reliability and precision make it suitable for use in applications such as telecommunications equipment, industrial systems, and consumer electronics where stable voltage regulation is critical.

Equivalent

The LT1764EQ-3.3 is a low dropout (LDO) linear voltage regulator. Equivalent products with similar specifications include the MIC29302 series from Microchip, the LM1085 from Texas Instruments, and the AMS1117 from Advanced Monolithic Systems. When selecting an equivalent, ensure it matches the input voltage range, output current, dropout voltage, thermal performance, and package type. Always consult datasheets for specific requirements.

Features

The LT1764EQ-3.3 is a low dropout (LDO) voltage regulator designed to provide a fixed output voltage of 3.3V. Key features include:
1. Low Dropout Voltage: It offers a dropout voltage of typically 340mV at a load current of 3A, which allows efficient operation even with low input-output voltage differentials.
2. High Output Current: Capable of delivering up to 3A of continuous output current, suitable for powering demanding applications.
3. Fast Transient Response: Designed to deal with rapid changes in load current, maintaining stable output voltage.
4. Adjustable Current Limit with Foldback: Provides overcurrent protection while minimizing power dissipation during fault conditions.
5. Thermal Shutdown: Protects the device from overheating by shutting down the output if the junction temperature exceeds a certain threshold.
6. Stable with Low ESR Capacitors: Ensures stability with a wide range of output capacitors, including low equivalent series resistance (ESR) types.
7. Good Line and Load Regulation: Maintains a stable output voltage over a range of input voltages and load conditions.
These features make the LT1764EQ-3.3 suitable for applications requiring efficient and reliable voltage regulation with a compact footprint.

Pinout

The LT1764EQ-3.3 is a low dropout (LDO) regulator with a fixed output voltage of 3.3V. It typically comes in a 5-pin TO-220 package. The pin functions are as follows:
1. VIN: This is the input pin where the unregulated voltage is supplied to the regulator.
2. GND: This pin is connected to the ground or common reference point of the circuit.
3. VOUT: This is the output pin where the regulated 3.3V voltage is provided.
4. ADJ/SET: Although the LT1764EQ-3.3 is a fixed output regulator, the ADJ pin is often used in adjustable versions. In this fixed version, it is internally configured for 3.3V output.
5. NC: This stands for "No Connection." It may be present in some packages but is not electrically connected to the internal circuitry.
The LT1764EQ-3.3 is used to provide a stable 3.3V output with low dropout voltage, suitable for applications requiring efficient power management.
