LP3982IMM-3.3/NOPB is a power management integrated circuit (PMIC) specifically designed to serve as a linear voltage regulator. It features a 3.3V voltage output and a quiescent current of 0.6mA. This product is designed to enhance system efficiency by providing accurate, low-power and low-drop voltage regulation.The LP3982IMM-3.3/NOPB is capable of providing a stable 3.3V output with a small quiescent current design, with an integrated current limit and an over-temperature shut-down. It offers a very wide input voltage range of 4.5V to 28V, allowing for flexibility and easy design integration. The device has a low drop out voltage (VOUT – VIN < 0.2V), making the power supply design simple.Applications of the LP3982IMM-3.3/NOPB mainly include automated equipment, surveillance camera, power-hungry instrumentation and medical products. It can also be used in various industrial and commercial products and for powering various embedded systems and microcontrollers. The LP3982IMM-3.3/NOPB features a constant voltage/current control down to as low as 2V and a soft-start or a fast transient response. The device also offers several protection features such as over-voltage protection, reverse-polarity protection, and over-temperature protection.Working PrincipleThe LP3982IMM-3.3/NOPB comprises of a voltage regulator, an amplifier, and a thermal protection circuit (TPC). The voltage regulator is responsible for maintaining a stable and accurate output voltage. It consists of a controllable current source, a reference voltage circuit, an error amplifier, and a bandgap reference. The amplifier perfectly balances the output voltage while the error amplifier ensures the bandgap reference is accurately regulated. The thermal protection circuit features a temperature sensor that activates a current source that turns on a transistor connected in series with the output stage. When the power supply is turned off, the device automatically enters a stand-by mode. The LP3982IMM-3.3/NOPB is a user-friendly device that is designed to deliver a low drop-out voltage, accurate voltage regulation and low quiescent current design, with a very wide operating temperature range from -40°C to 70°C. This device is ideal for applications requiring a stable voltage output and a large input voltage range with high efficiency.
