• Introduction

LP2966IMM-3336/NOPB is a 3.3V fixed outputlow drop out linear regulator from Texas Instrument, which operates from an input voltage of at least 2.7V to an output voltage of 3.3V. It has an ultra-low quiescent current of less than 0.75µA under no load conditions and draws up to a max of 270mA of output current at full load. Through its features, the device can solve numerous distinct applications and is available in SOT-23-5 and SOIC-8 packages.

• Application Field

LP2966IMM-3336/NOPB is extensively used in various applications such as low quiescent current regulators, battery chargers, motor control circuits, and energy supply systems, due to its ultra-low quiescent current, high efficiency, and fast response when the device operates under light load conditions. Its internal temperature shutdown leads to safety protection when the device operates over the specified temperature range. The device is also found in lightweight products such as wireless toys, portable medical equipment, and wireless media players, due to its low power dissipation and small size.

• Working Principle

The working principle of LP2966IMM-3336/NOPB can be understood in terms of the topology. It consists of a nominal 3.3V linear regulator with a high adjustable reference voltage, a voltage amplifier, and a supply decoupling capacitor. It functions as a current regulator circuit which provides a constant output voltage in the presence of varying load conditions. The voltage amplifier takes the input signal and amplifies it to a certain level using an external transistor. The output signal is then routed to a shunt regulator that acts as a current source. The current source then modulates the output current to achieve the desired output voltage value. Finally, the output voltage is fed to the load through a decoupling capacitor, which helps to reduce the voltage drop across the load and prevents excessive current fluctuations.

• Conclusion

In conclusion, LP2966IMM-3336/NOPB is a 3.3V low dropout linear regulator from Texas Instrument, which is capable of providing an output voltage of 3.3V from an input voltage of 2.7V. It has an ultra-low quiescent current, low power dissipation, fast transient response times, and is available in both SOT-23-5 and SOIC-8 packages. Due to its excellent performance and features, LP2966IMM-3336/NOPB is used in a broad range of applications such as low quiescent current regulators, battery chargers, motor control circuits, energy supply systems, wireless toys, and portable medical equipment.
