Linear Technology's LT3023EDD#TRPBF: Dual, Low-Noise, Low-Dropout Regulator

The LT3023EDD#TRPBF is a high-performance, dual-channel low-dropout linear regulator (LDO) designed and manufactured by Linear Technology, a company known for its precision electronic components. This regulator is specifically engineered to provide low-noise, clean power supply solutions for sensitive applications such as RF systems, precision instrumentation, and high-end audio equipment.

Each of the two independent LDOs within the LT3023EDD#TRPBF is capable of delivering up to 100mA of continuous output current with a low dropout voltage of only 300mV at full load, which makes it an excellent choice for systems where the input-to-output differential is minimal. The device operates with a wide input voltage range from 1.8V to 20V, offering flexibility for various design requirements.

The LT3023EDD#TRPBF comes in a compact 10-lead DFN package with a thermal pad for enhanced thermal performance. Its small form factor is ideal for space-constrained applications. The device also features a low quiescent current of 30µA per channel (operating) and less than 3µA in shutdown mode, which is beneficial for battery-powered devices where power efficiency is critical.

One of the standout features of the LT3023EDD#TRPBF is its low noise output, which is less than 20µV RMS over a 10Hz to 100kHz bandwidth. This, combined with the ability to use low-ESR ceramic capacitors for further noise reduction, ensures a clean and stable voltage supply. Additionally, the regulator provides excellent line and load regulation, maintaining consistent performance under varying conditions.

For protection, the LT3023EDD#TRPBF includes over-current and over-temperature protection features, ensuring the reliability and longevity of the device under harsh operating conditions. The regulator also offers independent shutdown control for each channel, allowing selective power management and further power conservation.

In summary, the LT3023EDD#TRPBF from Linear Technology is a versatile, dual-channel LDO regulator that offers low noise, low dropout, and high reliability, making it an ideal choice for applications that demand a clean and stable power supply.
