LP2996AMR/NOPB

LP2996AMR/NOPB application field and working principle

The LP2996AMR/NOPB is a low-cost, fixed output voltage, low-power voltage regulator for PMIC (Power Management Integrated Circuit) applications in the telecommunications, automotive, meshing and industrial domains. This device operates from an input voltage of 2.7 to 6.0 volts and its fixed output voltage options of 1.8 V and 2.5 V are ideal for applications where small amounts of current are needed. The LP2996AMR/NOPB is an ultra-low-power device, consuming only 5.5µA at no load, making it an ideal choice for battery-powered systems. The device also has low dropout voltage, typically 80mV, and low noise operation. This makes it suitable for powering low-power applications such as micro-controllers and FPGAs.

The LP2996AMR/NOPB device is designed using a bipolar process with two NPN transistors and two PNP transistors. The device is in the much-used three-terminal regulator package configuration, consisting of ground (GND), output voltage (Vout) and input voltage (Vin). The input voltage is also referred to as the Vcc or Supply voltage. The regulation of an output current is obtained by controlling the current flow between Vin and GND. This control is enabled by two separate stages of control: an input stage and output stage. The first stage of control is the input stage, which has the two NPN transistors. These NPN transistors are used to sense the input voltage and regulate the output voltage accordingly.

The second stage of control is the output stage, which has two PNP transistors to control the output current. The PNP transistors act as a constant current source, allowing for a constant current to be supplied to the output regardless of the input voltage. This feature of the microcontroller is what gives the device its low power consumption and improved efficiency over other voltage regulators.

The LP2996AMR/NOPB device is designed for low-power applications, but it can also be used in larger systems, where the input and output currents are higher. The current limit of this device is typically 150mA, although this can vary with variation in temperature and load. This device can be used in industrial, automotive, and meshing applications, and is suitable for various computing architectures including PC, Macintosh, and embedded systems.

The LP2996AMR/NOPB is packaged in the SOT23-6 package, with a junction temperature range of -40 to +125 degrees Celsius. The device is quite reliable and has an output noise of 20 mV or less. This voltage regulator is ideal for powering low-power, microprocessor-type systems, such as those used in cell phones, notebooks, and other similar applications.
