Maxim Integrated MAX8867EUK36+T Low-Dropout Linear Regulator

The MAX8867EUK36+T is a high-performance, low-dropout (LDO) linear regulator designed by Maxim Integrated, a leader in analog and mixed-signal engineering. This regulator offers a fixed output voltage of 3.6V, making it particularly suitable for battery-powered devices where efficient power management is crucial. The MAX8867 series is designed to deliver up to 150mA of continuous output current, which is ideal for portable electronics such as PDAs, mobile phones, and wireless equipment.

The device features a low dropout voltage, which enhances its efficiency by allowing it to operate closer to the battery voltage. This characteristic is especially beneficial in extending battery life in portable applications. The MAX8867EUK36+T also boasts a low quiescent current of just 120µA, which further conserves power when the device is in standby mode, and only 1µA in shutdown mode.

One of the key attributes of the MAX8867 is its thermal overload protection and short-circuit protection, which safeguard the device and the load from potential damage. The regulator also includes a low-battery warning that signals when the battery voltage falls below a preset threshold, providing an early indication for battery replacement or recharge.

The MAX8867EUK36+T comes in a compact SOT-23 package, which is highly valued for space-constrained applications. The small footprint of the package allows for a more streamlined design, freeing up board space for other critical components.

For design flexibility, the regulator does not require a bypass capacitor, although it is stable with ceramic output capacitors, which are smaller, more reliable, and have lower equivalent series resistance (ESR) compared to tantalum capacitors. This makes the MAX8867 an excellent choice for modern electronic designs that demand high performance in a small form factor.

In summary, the Maxim Integrated MAX8867EUK36+T LDO regulator is a reliable and efficient solution for a wide range of applications requiring a fixed 3.6V output. Its low dropout voltage, low quiescent current, and robust protection features make it a versatile component for any power management system.
