MAX1818EUT25#TG16

The MAX1818EUT25#TG16 is a low-dropout (LDO) linear regulator that offers a guaranteed 500mA load current with low dropout voltage. It operates from a +2.5V to +5.5V supply and delivers a stable output voltage that can be adjusted from 1.25V to 5.0V using an external resistive divider. This device is ideal for portable battery-operated equipment such as personal digital assistants (PDAs), cellular phones, cordless phones, base stations, and notebook computers.

Key Features:

1. Guaranteed 500mA Output Current: The MAX1818EUT25#TG16 provides a consistent 500mA of output current, making it suitable for a wide range of applications that require stable power delivery.
2. Low Dropout Voltage: With a dropout voltage of only 0.21V at 500mA, this regulator can efficiently convert input voltage to output voltage even when the input voltage is close to the output voltage.
3. Adjustable Output Voltage: The output voltage can be preset at internally trimmed voltages such as 1.5V, 1.8V, 2.0V, 2.5V, 3.3V, and 5V, or it can be adjusted from 1.25V to 5.0V using an external resistive divider. This flexibility allows the MAX1818EUT25#TG16 to be used in a variety of applications with different voltage requirements.
4. High Accuracy: The output voltage accuracy is ±1%, ensuring precise power delivery for sensitive circuits.
5. Compact Package: The MAX1818EUT25#TG16 comes in a miniature 800mW 6-pin SOT23 package, making it easy to integrate into compact designs.
6. Protection Features: The device includes over-current protection, short-circuit protection, and thermal shutdown protection to prevent damage in case of abnormal operating conditions.
7. Power OK Output: An active-low open-drain reset output indicates when the output is out of regulation, providing a convenient way to monitor the power supply status.

Applications:

• Notebook computers
• Cellular and cordless telephones
• Personal digital assistants (PDAs)
• Palmtop computers and base stations
