The MAX8864REUK+T is a linear voltage regulator device. It is a 3.2V to 5.5V low-Iq, low-dropout linear regulator, specifically designed to extend battery run time in portable applications where higher output currents are required. This device has a unique architecture and proprietary circuit design to deliver high accuracy and fast transient response. It is available in an 8-pin thermally enhanced TDFN and USON packages, where the USON package provides the best solution for small form factors and applications requiring extreme power efficiency.

The MAX8864REUK+T is designed for applications that require precise voltage regulation, or low input voltage operation, such as low-power, low-cost Microelectronic-Mechanical Systems (MEMS). It is primarily used in applications such as mobile phones, PDAs, portable gaming devices, and handheld barcode readers. The device is also widely used in medical, general purpose microcontroller, and power conversion applications.

The MAX8864REUK+T integrates a low-dropout linear regulator and an internal bipolar PMOS pass element to provide precise voltage regulation. The combination of a low-dropout linear regulator and a high-efficiency pass element reduces system cost and power dissipation while ensuring excellent line and load transient performance. The integrated PMOS pass element also provides excellent efficiency and clean output at light load current. This device is equipped with a 200mV internal reference that eliminates the need for an external reference component, resulting in a compact solution.

The MAX8864REUK+T supports output current up to 1.5A over an input voltage range of 3.2 to 5.5V. It features reverse current blocking and reverse voltage protection. The device offers short-circuit protection and has an over-temperature shut-down feature. It is designed to minimize the power dissipation and has a low dropout voltage of only 210mV at 1.5A. This device has excellent accuracy and is capable of providing an output voltage of 2.5V with ±0.7% accuracy over the -40°C to +85°C temperature range.

The MAX8864REUK+T is a low-power, low-dropout linear regulator ideal for cost-sensitive yet power-demanding applications that are battery power limited, such as mobile phones and handheld gaming devices. It is a small, low-cost solution with fast transient response, low dropout voltage, and high efficiency over a wide temperature range. It provides an output voltage accuracy of ±0.7% and features reverse current blocking for improved system protection.
