Analog Devices Inc. LT3015EDD-15#PBF Low Dropout Negative Linear Regulator

The LT3015EDD-15#PBF is a high-performance, low dropout negative linear regulator designed and manufactured by Analog Devices Inc. This robust regulator is specifically engineered to deliver a fixed output voltage of -15V with an output current capability of up to 1.5A. The LT3015 series is known for its high accuracy, low noise, and excellent power supply rejection ratio (PSRR), making it an ideal choice for precision, noise-sensitive applications.

The LT3015EDD-15#PBF comes in a compact DFN-10 (3mm x 3mm) package, which is suitable for space-constrained applications. It operates over a wide input voltage range from -1.8V to -30V, ensuring versatility across various negative voltage supply requirements. The device features an adjustable current limit, providing additional protection by preventing excessive currents that could potentially damage the regulator or the load.

One of the key advantages of the LT3015EDD-15#PBF is its low quiescent current, making it an excellent choice for battery-powered and energy-efficient systems. Its no-load quiescent current is typically 30μA, which minimizes power consumption when the load demand is low or in standby mode. Additionally, the regulator boasts a low dropout voltage, which enables it to maintain regulation with minimal difference between the input and output voltages, further improving efficiency.

The LT3015EDD-15#PBF also features an internal thermal protection circuitry, which shuts down the regulator to prevent damage from overheating. This thermal protection, along with the built-in current limiting and reverse battery protection, ensures reliable and safe operation under various conditions.

Applications for the LT3015EDD-15#PBF are diverse and include high-end instrumentation, medical equipment, industrial controls, and automotive electronics, where stable and reliable negative voltage supplies are critical. With its precise voltage regulation, low noise, and robust protection features, the LT3015EDD-15#PBF from Analog Devices Inc. is an optimal solution for designers looking to enhance the performance and reliability of their negative voltage power supply circuits.
