The MAX8511XK28 from Maxim Integrated is a high-performance, low-dropout (LDO) linear regulator designed to deliver a continuous 150mA output current. This precision voltage regulator offers an optimal solution for systems requiring a low voltage supply with a minimal input-to-output voltage differential.

Key Features

• Output Voltage: This device provides a fixed output voltage of 2.8V, making it suitable for various low-power applications.
• High Accuracy: The output voltage is accurate to within ±1.5%, ensuring reliable performance for sensitive electronic components.
• Low Dropout Voltage: The MAX8511XK28 boasts an ultra-low dropout voltage, typically just 165mV at full load, which enhances efficiency and allows operation over a wider range of input voltages.
• Thermal Overload and Short-Circuit Protection: Built-in safety features protect the device and the application from damage due to overheating or short-circuit conditions.
• Low Ground Current: The low ground current of only 110μA (typical) at no load helps to preserve battery life in portable applications.
• Stable with Ceramic Capacitors: The LDO is stable with ceramic output capacitors, which are smaller, more reliable, and have lower equivalent series resistance (ESR) than tantalum capacitors.

Applications

The MAX8511XK28 is ideal for battery-powered devices, portable equipment, and any application where power efficiency is a priority. It is commonly used in:

• Handheld Instruments
• Portable Media Players
• Wireless Handsets and Accessories
• PDAs and Palmtop Computers
