The LP3995A-30B3F is a low dropout (LDO) linear regulator manufactured by Lowpower. It's designed to provide a stable and regulated output voltage even when the input voltage is close to the desired output voltage. This LDO regulator is suitable for a wide range of applications, especially in battery-powered devices and systems requiring a clean and stable power supply. It offers a combination of low quiescent current, low dropout voltage, and small size, making it ideal for portable applications.

Applications:

• Battery-powered devices (smartphones, tablets, wearables)
• Portable medical devices
• Wireless communication devices
• Microcontroller power supplies
• Noise-sensitive circuits

Features:

• Low dropout voltage
• Low quiescent current
• Stable with ceramic capacitors
• Overcurrent protection (OCP)
• Thermal shutdown protection

Benefits:

• Extended battery life due to low quiescent current and low dropout voltage.
• Stable output voltage even with noisy input supplies.
• Reduced component count and board space due to stable operation with ceramic capacitors.
• Protection against damage from overload conditions due to the overcurrent protection.
• Protection against overheating due to the thermal shutdown protection.

Additional Details:

The LP3995A-30B3F provides a fixed output voltage of 3.0V with a typical accuracy of ±2%. It can deliver a maximum output current of 300mA. The dropout voltage is typically 150mV at 300mA. The quiescent current is typically 25μA. The device is stable with output capacitors as low as 1μF. The overcurrent protection (OCP) limits the output current during overload conditions. The thermal shutdown protection disables the output when the junction temperature exceeds a certain threshold. It is available in a small SOT-23 package. The operating temperature range is -40°C to +85°C. It offers excellent line and load regulation. It is also RoHS compliant.
