The LP2982IM5-3.3, designed and manufactured by Texas Instruments, is a high-performance, low-dropout regulator (LDO) specifically engineered to maintain a consistent 3.3V output voltage. This micro-power device is ideal for battery-powered applications due to its low power consumption and stable operation.

Key Features

• Output Voltage: Precisely regulated 3.3V output, which is essential for sensitive electronic components that require a stable voltage supply.
• High Accuracy: The output voltage tolerance is within ±0.5% at room temperature and ±1% over the entire temperature range, ensuring reliable performance under varying conditions.
• Low Dropout: With a very low dropout voltage, typically 280mV at full load, the LP2982IM5-3.3 ensures efficient operation even when the input voltage is close to the output voltage.
• Low Quiescent Current: The quiescent current is low, typically 28µA with a 10nA typical shutdown mode, which significantly extends battery life in portable applications.
• High Peak Current Capability: Capable of supplying up to 250mA of output current, the device can handle high peak demands with ease.
• Thermal Protection: Integrated thermal protection circuitry automatically shuts down the regulator to prevent damage from overheating.
• Noise Reduction: The LP2982IM5-3.3 includes a noise bypass pin for an optional noise reduction capacitor that minimizes output noise, a critical feature for RF and precision analog applications.
