Product Overview: MAX8867EUK30 - Maxim Integrated

The MAX8867EUK30 is a high-performance, low-dropout linear regulator (LDO) from Maxim Integrated, designed to deliver a continuous 150mA output current. This LDO is an ideal choice for portable battery-powered applications due to its low quiescent current and high-efficiency operation. The device comes in a compact SOT23-5 package, making it suitable for space-constrained applications.

Key Features

• Output Voltage: The MAX8867EUK30 provides a fixed output voltage of 3.0V, which is accurate to within ±1% over the entire operating temperature range.
• Low Dropout: It has a low dropout voltage of just 120mV at 150mA load, ensuring efficient operation even when the input voltage is close to the output voltage.
• High PSRR: With a high power supply rejection ratio (PSRR) of 70dB at 1kHz, the regulator significantly suppresses the input supply noise, providing a clean and stable output voltage.
• Thermal Protection: The MAX8867EUK30 includes built-in thermal shutdown protection that safeguards the device against overheating.
• Current Limit Protection: It also features current limit protection to prevent damage from overcurrent conditions.
• Low Quiescent Current: The device has a very low quiescent current of just 110µA, which helps to extend battery life in portable applications.
