PMIC - Voltage Regulators - LinearThe TPS799285DDCTG4 is a dual voltage linear regulator integrated circuit (IC) designed to supply current to low voltage circuits. It is a low dropout regulator (LDO) that can provide a constant current output of up to 500mA. The TPS799285DDCTG4 provides two adjustable, current limited, linear voltage regulation outputs with maximum outputripple of 40mV. The device is capable of providing both 3.3V and 5V to low voltage digital integrated circuits, allowing them to be powered from a single power supply.The TPS799285DDCTG4 package consists of two independent adjustable linear voltage regulators with current limiting protection and a thermal warning output. One channel is designed with an adjustable output that ranges from 1.20V to 4.40V and the other has an adjustable range from 2.60V to 3.75V. The device features an adjustable current limit setting from 75mA to 500mA with an output load regulation of 0.2%. The thermal warning output enables shut down of the device in case of over temperature enabling safe operation.The TPS799285DDCTG4 has a wide input voltage range, operating from 1.8V up to 6.0V, thus making it suitable for applications that are powered by different types of power sources. It also has an exceptional dropout voltage of 300mV, enabling the device to maintain output voltage even at minimum supply voltage. Furthermore, the device integrates short-to-ground, short-to-battery, and short-circuit protection, making it suitable for a range of industrial and consumer applications.The TPS799285DDCTG4 is designed for use in a wide range of applications, including digital video and imaging equipment, Wi-Fi devices, medical devices, automotive electronics, GPS systems, and industrial devices. As a high efficiency and low dropout voltage regulator, it is ideal for providing power to low voltage circuits from a single supply.The working principle of the TPS799285DDCTG4 is quite simple. It utilizes the linear regulation principle to control output voltage. Basically, the device uses an internal series regulator, with an adjustable voltage reference and an internal power transistor, to set the output voltage of the device. The transistor should be able to provide sufficient current to drive the load, while keeping the output voltage to the desired set point.The device\'s current limiting protection ensures that the regulator will not be damaged by an overloaded output. In case the current is excessive, the current limit circuitry will turn off the output transistor to prevent damage to the device from overloading. The adjustable current limit feature also allows users to set the current output level according to the load.The thermal warning output is a feature of the TPS799285DDCTG4 which avoids over temperature situations. If the junction temperature of the IC exceeds the specified level, the thermal warning output will be activated and the user can be alerted of the over temperature situation. The junction temperature is monitored by the thermal shutdown circuitry, and if it exceeds the specified level, the output will be turned off and re-enabled when the temperature falls back to the normal level.In short, the TPS799285DDCTG4 is a highly efficient and feature-rich dual voltage linear regulator IC, which is capable of providing reliable, precise and stable current to low voltage circuits. It has a wide input voltage range and adjustable current limiting protection and thermal warning capabilities, making it ideal for a variety of applications.
