The LP2981AIM5X-2.8/NOPB is a high-performance, low-dropout regulator (LDO) from Texas Instruments, designed to maintain precision voltage control in a variety of applications. This micro-power device is particularly suitable for battery-powered systems due to its low quiescent current and low dropout voltage, ensuring minimal power loss and extended battery life.

Key Features

• Output Voltage: Fixed at 2.8V, providing a stable and regulated output for consistent performance.
• High Accuracy: Output voltage accuracy is maintained within ±0.5%, ensuring reliable operation for sensitive electronic components.
• Low Dropout: With a typical dropout of just 280mV at 100mA, this LDO can operate efficiently even when the input voltage is close to the output voltage.
• Low Quiescent Current: An extremely low quiescent current of 28µA (typical) during operation, and 1µA (typical) in shutdown mode, makes this regulator ideal for portable and battery-operated devices.
• High Peak Current Capability: Capable of delivering up to 100mA of output current, sufficient for a wide range of applications.
• Thermal Protection: Integrated thermal shutdown protection prevents damage from overheating.
• Stable with Low-ESR Capacitors: Stable with ceramic capacitors as low as 1µF, providing flexibility in design and reducing overall component size.
