LM2936QMMX-5.0/NOPB - Ultra-Low Quiescent Current LDO Voltage Regulator

The LM2936QMMX-5.0/NOPB is a high-quality, highly reliable low-dropout voltage regulator from Texas Instruments, designed to deliver a fixed output voltage of 5.0V with ultra-low quiescent current. This regulator is ideal for battery-powered applications where extending battery life is crucial. Its quiescent current is exceptionally low, typically only 15μA, which helps to minimize the power consumption when the device is in standby mode.

Encased in a compact SOT-23 package, the LM2936QMMX-5.0/NOPB is capable of supplying an output current of up to 50mA, making it suitable for small electronic devices such as remote sensors, microcontrollers, and memory standby circuits. The regulator's ability to maintain a stable output voltage with a drop of less than 0.4V at full load is a testament to its efficiency and robustness.

This regulator features a unique "Zero-CURRENT" shutdown mode, which further reduces the quiescent current to virtually zero when the device is not in use, thus conserving energy to an even greater extent. This makes the LM2936QMMX-5.0/NOPB an excellent choice for energy-sensitive applications where every microampere of current consumption counts.

The LM2936QMMX-5.0/NOPB also includes built-in protection features such as thermal shutdown and current limiting, ensuring the safety and longevity of the device under various conditions. These features protect both the voltage regulator and the application circuitry from potential damage due to overheating or overcurrent situations.

For design flexibility, the regulator does not require an external capacitor for stability, which simplifies the circuit design and can help reduce the overall bill of materials. However, it remains compatible with ceramic, tantalum, or aluminum electrolytic capacitors on the output if additional filtering is desired.

The NOPB designation in the part number indicates that the product is lead-free and RoHS compliant, making it suitable for use in environmentally sensitive applications and in jurisdictions where regulations restrict the use of hazardous substances.

With its combination of low power consumption, stable performance, small footprint, and environmental compliance, the LM2936QMMX-5.0/NOPB from Texas Instruments is an excellent choice for designers looking to optimize their power management solutions in portable and battery-powered systems.
