The MAX8864TEUK+T is a linear regulator from the PMIC Voltage Regulator family, providing flexible performance in both fixed and adjustable voltage architectures. This voltage regulator supports battery charging for applications such as cellular phones, digital cameras, portable devices, and battery-powered consumer electronics.

The MAX8864TEUK+T has a wide input voltage range (2.7V to 15V), and can deliver an output voltage of 1.8V to 14V. It can provide up to 500mA of current, with an output current accuracy of +/-1.5%. With an internal frequency compensation loop and a fast transient response, this regulator achieves fast load regulation, providing a controlled output in the presence of changing load conditions.

The MAX8864TEUK+T is equipped with built-in over-voltage ,under-voltage, and over-temperature protection on the output voltage, ensuring robust, reliable performance. It also features short circuit and over-current protection. This regulator also features power-on reset (POR) circuitry, providing a low-power standby supply.

The MAX8864TEUK+T has a wide operating temperature range of -40°C to +85°C, making it suitable for a range of environmental conditions. This regulator is also available with a fixed output voltage, enabling designers to create robust systems that adhere to industry-standard voltage requirements.

The MAX8864TEUK+T uses a linear regulator approach to voltage regulation. This is a simple and efficient regulator configuration in which the output voltage is directly proportional to the input voltage, with no switching involved. The regulator circuit uses two transistors and two resistors, with the input voltage being applied symmetrically across the two resistors. When the output voltage is lower than the desired level, current flows through the transistor’s base-emitter junction, generating an amplified voltage that is applied to the control gate of the second transistor. This causes the voltage across the second transistor’s base-emitter junction to drop, which adjusts the output voltage to the desired level.

In summary, the MAX8864TEUK+T is a flexible voltage regulator from the PMIC Voltage Regulator family. This device offers wide input voltage range, up to 500mA of current, short-circuit protection, over-voltage and under-voltage protection, and over-temperature protection on the output voltage. It also features power-on reset (POR) circuitry, providing low-power standby operation. This regulator uses a linear regulator approach, and is operated over a wide temperature range of -40°C to +85°C.
