As the world continues to advance, many products are becoming increasingly specialized, and the LTC3621IMS8E-3.3#PBF is no different. This voltage regulator belongs to PMIC (Power Management Integrated Circuits) — more specifically, Voltage Regulators and DC DC Switching Regulators. It is a highly specialized regulator that is meant for specific applications.
The LTC3621IMS8E-3.3#PBF is a specialized regulator that excels at low dropout voltage regulation. Its primary offering is the ability to precisely regulate output voltages from 0.8V to 4.5V over a wide input voltage range. Because of its low dropout voltage, the LTC3621IMS8E-3.3#PBF is ideal for applications where high efficiency, tight regulation, and a small footprint are required. The regulator also offers an ultra-low quiescent current of 50µA, suitable for system-level power saving. Other features that make the LTC3621IMS8E-3.3#PBF ideal for power-sensitive applications are an accurate ±1.5% reference voltage tolerance, 9kHz switching frequency, over-current protection, and an adjustable soft-start feature. When coupled with its small SC-74A or SOT-23-6 packages, the LTC3621IMS8E-3.3#PBF is suitable for meeting a variety of space-sensitive power requirements.
The LTC3621IMS8E-3.3#PBF is a switched output voltage regulator, and it operates by switching on and off at a fixed rate. The switching rate is determined by a frequency divider, and the duty cycle is set to maintain a constant output voltage. This method of regulation is considered to be more efficient than linear regulators, and it is usually used in larger voltage conversion applications. The switching output voltage can be set to one of three output voltage ranges (1.2V/2V to 3.3V/3.3V, 1.2V/2V to 5V/3V, or 1.2V/2V to 4.5V/3V) depending on the input voltage.
The LTC3621IMS8E-3.3#PBF is one of the lowest energy solutions available for applications requiring ultra-low dropout voltage regulation. Its accuracy and efficiency make it a perfect choice for a variety of power-sensitive systems. Its wide input voltage range, accurate reference voltage tolerance, and low dropout voltage make it suitable for applications such as battery management, Bluetooth/RFID tags, printers, microcontrollers, digital cameras, point of sale (POS) terminals, and mobile phones. Its small size and low quiescent current also makes it suitable for portable or battery-powered applications.
In conclusion, the LTC3621IMS8E-3.3#PBF is a specialized voltage regulator that is perfect for low dropout voltage regulation applications. It has wide input voltage range, an accurate reference voltage tolerance, high efficiency, and a small footprint. It is perfect for battery management, Bluetooth/RFID tags, printers, microcontrollers, digital cameras, point of sale (POS) terminals, and mobile phones. Its low quiescent current is suitable for power saving, and it is the perfect choice for applications requiring ultra-low dropout voltage regulation.
