TPS76833QPWP is a fully-integrated, low quiescent current, ultra-small high performance linear regulator that is placed in the product line of voltage regulators and PMICs by Texas Instruments (TI). This device is a prime example of advanced design and engineering that provides a powerful, cost-effective solution for many industrial application fields and areas.The TPS76833QPWP is designed to power embedded hosts and other low-voltage applications that need stringent performance requirements and a small footprint. Its efficiency – both in terms of power and area savings – alongside its micro-power mode make it a great fit for many of today’s ever-more sophisticated, miniaturized PCBs.The TPS76833QPWP provides voltage regulation over a wide range of operating settings with a programmable supply current and high output accuracy, as well as tight load and line regulation with low quiescent current. It also features current limit, short-circuit protection, and thermal shutdown.This device’s features can be broken down into further categories:Inputs & Outputs: At the input- and output-level, the TPS76833QPWP offers a wide range of operating settings including an input voltage of 3.1V to 5.5V, an output voltage that can be programmed by external resistors, and an adjustable output current of 10mA to 40mA. To optimize the device’s utilization, its output voltage can be programmed to be different from its input voltage.Efficiency: Efficiency is a key indicator of power consumption, and the TPS76833QPWP offers great performance in this regard. The device incorporates a proprietary architecture design with low dropout voltage and can achieve a power-supply efficiency of 96%.Size: The ability to save space and achieve a small form factor is critical in contemporary engineering designs. However, designers often face trade-offs in power consumption, efficiency, and performance when attempting to do so. The TPS76833QPWP solves this problem by providing an ultra-small High-Performance Linear Regulator (HPLR) solution in a miniature 2x2mm WCSP package.Power Management: Power management is a key feature of the TPS76833QPWP which helps to achieve better utilization of resources. It features a low quiescent current, programmable supply current (up to 40mA), and a shutdown mode that allows the power supply to be cut while preserving the output voltage. Moreover, the TPS76833QPWP also offers programmable slopes that enable more precise current delivery.These features enable the TPS76833QPWP to provide up to 96% efficiency in typical applications and performance that surpasses that of competing parts. Its small dimensions and power management capabilities provide great flexibility and system cost savings, making the device suitable for a wide range of applications, including television displays, digital signage, medical, telecom, and industrial equipment.Working PrincipleThe TPS76833QPWP device works on the principle of linear voltage regulation. It regulates the output voltage of the device by controlling the amount of current that is drawn from the input at any given time. The output voltage is determined by the settings of the external resistors that are connected to the device’s output.The device works by sensing the output voltage, comparing it to the reference voltage, and then modifying the input current to bring the output voltage to the desired level. This process is repeated in cycles to ensure a stable output voltage throughout operation.The TPS76833QPWP also works to minimize the current consumed by the device. It does this by shutting down the device in ‘sleep mode’ when the output voltage reaches the reference voltage. This helps reduce the overall power consumption and extends the battery life of the device.The device also offers a shutdown mode which can be used to reduce the operating power when the device is not in use. This can be beneficial for applications such as medical devices and industrial equipment where power is a critical factor.ConclusionThe TPS76833QPWP is a high-performance, ultra-small linear voltage regulator that provides excellent performance, tight regulation, and low operating current. Its output voltage and current can be programmed to provide an optimal and efficient power source, while its Sleep mode and low quiescent current help to further reduce the total power consumption of the system and ensure longer battery life. The device is an excellent choice for applications such as television and digital signage displays, medical equipment, telecommunication gadgets, and industrial electronic systems.
