Product Overview: LP2966IMM-3333/NOPB

The LP2966IMM-3333/NOPB is a high-performance, dual-output low-dropout regulator (LDO) from Texas Instruments, designed to provide precise voltage regulation with minimal power loss. This LDO is particularly suitable for battery-powered applications due to its low quiescent current and high efficiency, which help to extend battery life.

Key Features

• Dual Output Voltage: This device has two regulated outputs, both fixed at 3.3V, which can deliver up to 150mA of output current each. This feature makes it ideal for systems that require multiple regulated voltages from a single power source.
• Low Dropout Voltage: The LP2966IMM-3333/NOPB boasts a low dropout voltage, ensuring efficient operation even when the input voltage is close to the output voltage, which is critical for maximizing battery life in portable devices.
• High Accuracy: The output voltage is guaranteed to be within ±1% of the specified voltage at room temperature, and within ±3% over the full operating temperature range. This high accuracy is essential for sensitive electronic components that require stable power supply.
• Low Quiescent Current: The device features a low quiescent current, typically 80µA per output, which reduces power consumption when the device is in standby mode.
• Stable with Low ESR Capacitors: The LP2966IMM-3333/NOPB is stable with ceramic capacitors, which have lower equivalent series resistance (ESR) than tantalum capacitors. This allows for the use of smaller, cheaper, and more reliable capacitors.
• Thermal Shutdown and Current Limit Protection: Built-in safety features include thermal shutdown to protect the device from overheating, and current limit protection to prevent damage from output overcurrent conditions.
• Surface-Mount Package: The device comes in a small 8-pin VSSOP (MSOP) package, which is suitable for space-constrained applications.
