MAX8869EUE25+

MAX8869EUE25+ Description

The MAX8869EUE25+ from Analog Devices Inc./Maxim Integrated is a high-performance, low-dropout (LDO) linear voltage regulator designed for precision power management in demanding applications. This 1A output regulator supports an adjustable output range of 0.8V to 5V (with a fixed 2.5V option), making it versatile for both low-voltage and standard power rails. Its 5.5V maximum input voltage ensures compatibility with common power sources, while advanced control features like enable, reset, and soft start enhance system reliability. The device is housed in a compact 16-pin TSSOP package, ideal for space-constrained designs.

MAX8869EUE25+ Features

• High Efficiency & Low Quiescent Current: Operates with just 2 mA quiescent current (Iq) and 2.5 mA supply current, optimizing battery life in portable applications.
• Exceptional PSRR: Delivers 54dB at 100kHz, minimizing noise in sensitive analog/digital circuits.
• Robust Protection: Integrated safeguards include over-current, over-temperature, and short-circuit protection for enhanced system durability.
• Flexible Control: Features enable/shutdown, reset monitoring, and programmable soft start to prevent inrush current and ensure orderly power-up sequences.
• Wide Operating Range: Supports 0.8V–5V adjustable output (fixed 2.5V variant available), catering to diverse voltage requirements.
• Compact & Reliable: MSL 1 (Unlimited) moisture sensitivity and RoHS3 compliance ensure long-term reliability in industrial environments.
