The LP3962ES-3.3 is a 1.5A low dropout linear regulator providing a fixed 3.3V output. With a dropout voltage of just 0.55V at full load, it efficiently regulates from 5V rails. The DDPAK/TO-263-5 package offers excellent thermal dissipation for continuous operation. Its 10 mA quiescent current balances performance and efficiency, making it suitable for industrial and automotive applications.
- 1.5A Output Current: Powers multiple ICs on a 3.3V rail without additional regulation stages.
- Low Dropout (0.55V @ 1.5A): Reduces power dissipation and allows operation from 4V inputs.
- Robust TO-263-5 Package: Ensures reliable thermal performance in high-temperature environments.
- Stable Fixed 3.3V Output: Eliminates the need for external resistor dividers, simplifying design.
Post-Regulation for Switching Supplies
The 1.5A capacity and 0.55V dropout make it ideal for cleaning up noisy 5V switching outputs to a stable 3.3V rail.
FPGA and CPLD Power
Many FPGAs require 3.3V I/O banks. The LP3962ES-3.3 provides low-noise power with sufficient current for multiple I/O banks.
Automotive Infotainment
In car audio and navigation systems, the TO-263 package handles thermal stress, while the 3.3V output powers codecs and processors.
Industrial Sensors
For 3.3V sensor interfaces in PLCs, this regulator offers reliable operation over temperature with minimal output deviation.
Networking Routers
Routers need stable 3.3V for PHY chips. The low dropout ensures regulation even with input fluctuations from upstream DC-DC converters.
Medical Monitoring Devices
Patient monitors use 3.3V for analog front-ends. The low noise characteristics help maintain signal accuracy.
