Product Overview: MAX821LUS+T from Maxim Integrated

The MAX821LUS+T is a high-performance, low-dropout linear regulator (LDO) designed to deliver a continuous output current up to 150mA. Manufactured by Maxim Integrated, a leader in analog and mixed-signal products, this LDO is well-suited for portable electronic devices where energy efficiency and space constraints are primary concerns.

This regulator features a low dropout voltage, which ensures efficient operation even when the input voltage is very close to the output voltage, thereby maximizing battery life in portable applications. The MAX821LUS+T operates over a wide input voltage range from +2.5V to +11V, making it versatile for various circuit designs.

The device comes in a compact SOT-23 package, which is ideal for space-constrained applications such as mobile phones, PDAs, and other handheld devices. Its small footprint also makes it an excellent choice for PCB designs where board space is at a premium.

With a fixed output voltage variant, the MAX821LUS+T offers a stable and precise voltage supply, which is critical for sensitive electronic components. The regulator's thermal overload protection ensures reliable operation by shutting down the output when the internal junction temperature exceeds safe limits, thereby protecting the device and the system from damage due to overheating.

Moreover, the MAX821LUS+T includes features such as a low quiescent current, which is beneficial for battery-powered devices as it minimizes power consumption when the device is in standby mode. Additionally, the device has a fast transient response, which helps maintain a stable output voltage during rapid changes in load, ensuring consistent performance for the powered device.

Overall, the MAX821LUS+T from Maxim Integrated is an excellent choice for designers looking for a reliable, high-performance LDO regulator that offers both space savings and energy efficiency. Its robust feature set and compact design make it suitable for a wide range of applications, particularly where battery life and form factor are critical considerations.
