Application Field

TPS75325QPWPR can be conveniently used in many portable and mobile applications that require low voltage and low noise power supply, such as handheld consumer electronic products, cell phones or PDA, or notebooks. TPS75325QPWPR can also be used as a voltage switch within a supply. For example, it can be set up to provide a 0.5V rail when the main supply is above 3.3V, and a 1.2V rail when the main supply drops down to 1.8V. These features make TPS75325QPWPR a good choice for battery powered applications where the supply voltage can change in a wide range.

Working Principle

TPS75325QPWPR integrated circuit has an internal voltage reference, an error amplifier and a P-Channel MOSFET to work as a voltage regulator. The voltage regulated is set by an external resistor divider network. The voltage reference is typically 2.5V, and the internal error amplifier is generated to deliver error signals with closed loop feedback. The P-In MOSFET will then adjust the output voltage to meet the requirement based on the control signals from the error amplifier. The error amplifier is then used to control the MOSFET switch with advanced tweaking techniques.

TPS75325QPWPR has other features, such as internal fault protection and logic signals, that are useful in many applications. Its protection circuit includes overvoltage protection (OVP), undervoltage protection (UVP), current limit protection, and thermal shutdown protection. All these features together come along well to form a voltage regulator with excellent performance.

Conclusion

In summary, Texas Instruments TPS75325QPWPR is a PMIC that belongs to the Voltage Regulators – Linear category. It is suitable for applications that require accurate, low quiescent current, low noise power supply and can generate output voltages ranging from 0.5V up to 3.5V with a wide input range of 1.8V to 6V. TPS75325QPWPR is particularly suitable for portable and mobile applications that require low voltage supplies such as handheld consumer electronic products or cell phones/PDAs.
