Prime power management integrated circuits (PMICs) are one of the most critical components in an electronic device as they contribute to the system\'s overall performance and quality. PMICs enable a device or system to shift between several power sources or voltages, and ultimately dictate their overall effectiveness. PMICs consist of an array of components, and one of the most important subgroups of PMICs are linear voltage regulators (LVRs). The NCV8133BMX100TCG is a high-performance, low-dropout (LDO) linear voltage regulator chip that is ideal for any system that requires a stable, low-voltage power output. This article will cover the NCV8133BMX100TCG\'s application field and working principle.

Application Field

The NCV8133BMX100TCG regulator is a robust, ultra-small LDO voltage regulator capable of providing a precise, regulated output voltage even under extreme conditions. It is designed to support a wide input voltage range, from minimum 1.8V to maximum 6.5V, and it can generate an output voltage from 0.9V to 5.5V. The ultra-small size of the chip, at 3.2mm x 3.2mm, makes it a great choice for embedded systems, wearables, and other portable applications that require a compact form factor. Additionally, its improved thermal performance of -40°C to +125°C junction temperature allows for use in automotive and other harsh-environment applications.

The NCV8133BMX100TCG\'s integrated short-circuit and thermal protection features ensure that the device is protected from damage while also meeting the strictest safety regulations. The device is also AEC-Q100 qualified and has excellent EMI compliance, ensuring no interference with other electronics in system. The low operating quiescent current of 17µA in shutdown mode and its low duty-cycle operation make it suitable for battery-powered applications.

Working Principle

As an LDO voltage regulator, the NCV8133BMX100TCG contains a PNP current-steering transistor operating as a driver along with a reference voltage source connected to a feedback pin. The control mode of the regulator is voltage-mode control and the compensation loop is externally compensated using an external capacitor. The feedback of the device is shared with an external low-pass filter, consisting of a resistor and a capacitor connected in series, to stabilize the loop.

The LDO voltage regulator works on the principle of comparing the output voltage with reference voltage. A comparator compares the two and as soon as the output voltage reduces, the output of the comparator rises, thereby controlling the PNP current-steering transistor. The PNP transistor then amplifies the difference between the two voltages, thus regulating the output voltage.

The NCV8133BMX100TCG also has a few other features that help enhance its performance and convenience. It has an independent enable pin for easy control of the regulator and a power-good indication pin that indicates when the output voltage has reached its specified voltage. Additionally, an internal resistor dividers allows the device to be used in multiple output voltages, meaning you can simply program the device for the required output voltage.

The NCV8133BMX100TCG is an excellent solution for systems requiring a low-voltage, accurate power source. With its wide input voltage range, integrated protection features, low operating current, and low EMI, the NCV8133BMX100TCG provides a stable, reliable power source that meets the toughest safety standards and applications.
