TPS7248QP Application Field and Working Principle

The TPS7248QP is a Linear voltage regulator from Texas Instruments in the family of PMIC – Voltage Regulators – Linear. It is a Low-Dropout voltage regulator, a kind of regulator designed to regulate a lower voltage than typical three-point regulators, by allowing the output voltage to drop by a maximum of 1.2V (the Dropout voltage).

The TPS7248QP is suitable for powering precision circuits such as Instrumentation and High-Frequency datacom applications. It can also be used as a Voltage Reference in DACs and in Switch Mode applications such as High-Voltage converters or Negative Rail Supplies. It is also useful for powering displays which need a steady voltage despite large load transients.

The TPS7248QP has a maximum input voltage of 30V and a maximum output voltage of 28V. It’s output current is 1.5A and it can deliver up to 25W of power. It is designed to operate over a temperature range of -20C to +125C. It has Internal Overcurrent protection as well as Short-Circuit Protection, which makes it easy to use a circuit to protect your system from power related problems.

The TPS7248QP operates by combining a high current, low dropout Linear regulator with a Charge Pump Converter, which is responsible for generating a higher voltage at the regulator output. The Charge Pump Converter uses a small number of components, and therefore is able to deliver a high power efficiency. The combination of the LDO and the charge pump Converter allows for good regulation and ripple suppression, with a maximum output voltage accuracy of ±2%. This, combined with the low noise of the LDO and the fast response time of the charge pump converter, makes it the ideal regulator for systems requiring high performance and accuracy.

The input and output of the regulator are protected from transients by a series of capacitors, and the output of the regulator is protected from reverse voltages. The TPS7248QP also has an active current-limit protection which can protect against over-current conditions. The device is also protected against reverse voltages by an Internal Fuse and by a Zener diode.

In summary, the TPS7248QP is a robust, high-power and high accuracy linear voltage regulator with low dropout and protection against overvoltages, short circuits and reverse voltages. It is ideal for powering precision circuits and applications requiring high performance and accuracy. It is also suitable for powering display panels, as it is able to deliver a reliable voltage despite large load transients.
