The TPS77518PWPG4 is a linear voltage regulator with up to 3 A output current and up to 18 channels. In the power management integrated circuits (PMIC) market, linear regulators are a niche product, and the TPS775 family contributes to filling that gap. These devices are typically used in applications such as low voltage microcontrollers (MCUs), digital signal processors (DSPs), and other applications that need to control power at a low voltage.

The TPS77518PWPG4 is a low dropout regulator that can provide supply voltages up to 18 V and the devices in the series feature individual and parallel programmable current limit and over voltage protection (OVP) circuits. The device can be operated in single or dual supply mode and offers various features, including adjustable output voltage, low quiescent current and high line regulation, as well as high output accuracy and low dropout voltage. It also has a high peak current rating and can achieve ±2% output accuracy.

The TPS77518PWPG4 is designed to deliver reliable, low-cost voltage regulation for a variety of applications, including automotive, industrial, communication, and battery-powered systems. It is ideal for supplying a regulated voltage to microcontrollers, digital signal processors, instrumentation, power-line sensing, and more. It has a wide input voltage range of 5.25 V to 18 V and a low quiescent current of 3 μA. The device offers high line and load regulation and low dropout voltage. It also offers built-in protection against short circuits, over-voltages, and over-temperatures.

The device includes a voltage reference, series pass transistor, error amplifier, and other components on a small footprint. This allows for the device to operate with high line and load regulation and low noise. In addition, the device can be operated from a wide range of voltage and current combinations. The device is available in a micro size 6-pin TSOT-23-6 package and is designed to work at temperatures up to 85°C.

The TPS77518PWPG4 operates using an error amplifier system. This allows it to maintain a constant output current level, regardless of the input voltage. The fixed reference voltage is compared to the output voltage and an error signal is generated. This error signal is then compared to the reference voltage, and the difference determines the output current level. This output current level is controlled by the error amplifier, in the same way that a given current level is controlled by a given voltage. Consequently, the input voltage range can be adjusted to match the required output voltage and current.

The device includes built-in OVP protection circuitry and current limit protection for short-circuit conditions. This helps protect the device from catastrophic failures in the event of an over-voltage or short-circuit conditions. Additionally, the device can operate in single or dual supply mode, and provides a wide range of programming options. This includes adjustable voltage output, adjustable current limit and over-voltage protection.

The TPS77518PWPG4 is a great solution for low voltage microcontroller applications, digital signal processing, power management, and other applications that need to regulate power. Its low quiescent current, wide input voltage range, and protection features make it suitable for a variety of applications. Its low cost, low noise operation, and small footprint make it an ideal choice for cost-sensitive applications.
