Frequently Asked Questions
What is the output voltage and current rating of the LP3964ES-3.3?
The LP3964ES-3.3 provides a fixed 3.3V output voltage and supports up to 800mA of output current, making it suitable for powering microcontrollers, FPGAs, and other medium-load digital circuits.
What is the dropout voltage of the LP3964ES-3.3 and why does it matter?
The LP3964ES-3.3 has a typical dropout voltage of 0.24V and a maximum of 0.35V at full load. This low dropout characteristic allows the regulator to maintain a stable 3.3V output even when the input supply drops to as low as 3.65V, which is critical for battery-powered applications near end-of-discharge.
What package does the LP3964ES-3.3 come in and what are its thermal advantages?
The LP3964ES-3.3 is housed in a TO-263 (D²PAK) 5-pin surface-mount package. This package offers an exposed thermal pad that allows efficient heat dissipation to the PCB, enabling the device to handle higher power dissipation compared to smaller packages like SOT-23 or SOIC.
What are common applications for the LP3964ES-3.3?
Typical applications include powering 3.3V logic rails in embedded systems, industrial controllers, automotive electronics, portable handheld devices, IoT nodes, and telecommunications equipment where a reliable low-dropout regulator with moderate current capacity is required.
Are there compatible replacements or alternatives to the LP3964ES-3.3?
Compatible alternatives include other 3.3V fixed LDO regulators such as the LP2985-3.3, TLV1117-3.3, and LM1117-3.3. When substituting, verify the dropout voltage, maximum input voltage, output current rating, and package footprint to ensure drop-in compatibility with your design.
