TPS72015DRVR

PMIC - Voltage Regulators - Linear

The TPS72015DRVR is a low-dropout (LDO) voltage regulator designed to deliver up to 2A of continuous output current. It is part of TI\'s green power management integrated circuits (PMICs) portfolio. This device offers a wide input voltage range of 2.65V to 5.5V and fixed output voltage options of 1.2V to 3.3V.

The TPS72015DRVR features excellent power conversion performance of 99.1% minimum line regulation and 99.8% maximum load regulation. Its quiescent current is just 20μA in bypass mode making it an excellent choice for applications requiring ultra-low power. This device includes enable and a power-good signal that offers superior system monitoring capabilities. Other features include over-current protection and over-temperature protection.

The TPS72015DRVR is best suited for applications such as cellular and smartphone basebands, automotive infotainment systems, wearables and IoT, LCD drivers and portable/handheld devices.

Working Principle

The TPS72015DRVR is a high-precision linear voltage regulator with a wide range of input and output voltages. It operates by stepping down the input voltage and providing the desired output voltage. The device features a low-noise power oscillator (LPO) that enables the regulator to switch at a very low frequency. This is important to minimize switching noise and reduce the power consumption.

The device features an internal compensation circuit that ensures optimal loop performance throughout the entire operating range. This compensator ensures a quick response to load step changes as well as a low-noise and low-ripple output. In addition, the device includes a power-good signal to indicate when the output voltage is within the specified operating range.

The device has an over-current protection function that shuts down the output and prevents the output from exceeding the safe current limit. It also has an over-temperature protection (OTP) circuit that shuts down the output in the event of an over-temperature condition.

Conclusion

The TPS72015DRVR is an advanced low-dropout voltage regulator designed to deliver up to 2A of continuous output current. It features excellent power conversion performance, ultra-low quiescent current, enable and power-good signal, and over-current and over-temperature protection circuit. The device offers the right combination of features and performance for applications such as cellular and smartphone basebands, automotive infotainment systems, LCD drivers and portable/handheld devices.
