The LT3024IFE from Linear Technology is a high-performance dual low dropout (LDO) regulator designed to deliver precision voltage regulation with extremely low noise operation, making it ideal for sensitive RF and analog circuitry. This regulator features two independent LDOs, each capable of supplying 500mA of output current with a low dropout voltage of only 300mV at full load.

Key Features

• Low Noise Output: The LT3024IFE boasts a very low output noise of only 20µVRMS over a 10Hz to 100kHz bandwidth, ensuring clean and stable power supply for noise-sensitive applications.
• Wide Input Voltage Range: This regulator operates with an input voltage range from 2.7V to 20V, providing flexibility for various design requirements and ensuring compatibility with a broad range of input sources.
• Independent Channels: Each of the two LDOs has its own separate input, enabling the use of different input voltages for each regulator if necessary.
• Adjustable Output Voltage: The output voltage for each channel is adjustable from 1.22V to 20V, allowing for precise voltage regulation tailored to specific circuit demands.
• Stable with Low ESR Ceramic Capacitors: The LT3024IFE remains stable with ceramic output capacitors, which are smaller, more reliable, and have lower equivalent series resistance (ESR) compared to tantalum or aluminum electrolytic capacitors.
• Over-Current and Over-Temperature Protection: Built-in protection features safeguard the device against adverse conditions, enhancing the longevity and reliability of both the regulator and the overall system.
• Thermal Shutdown: An integrated thermal shutdown mechanism triggers when the device reaches a certain temperature threshold, preventing damage from overheating.
• Package Options: The LT3024IFE is available in a 16-lead thermally enhanced TSSOP package, which ensures efficient heat dissipation and a compact footprint for space-constrained applications.

Applications

The LT3024IFE is particularly well-suited for applications that demand clean, reliable power with minimal noise interference. This includes precision instrumentation, medical equipment, telecommunications, and portable electronics. Its dual independent LDO architecture makes it a versatile choice for powering multiple voltage rails in complex systems.
