TPS79325YZQR linear voltage regulator is a low-power, low-dropout regulator, fully integrated with a low-side TrenchFET® power MOSFET. It is designed for use in space limited portable or pager applications or in systems with multiple output voltages such as DVD players or PDAs. The regulator has an operating input voltage range from 2.7V to 12V and a fixed output voltage from 0.94V to 2.5V with a maximum rated load current of 1.5A. In addition, the regulator has an adjustable output voltage from 0.94V to 2.5V. The line and load regulation is 0.03% and 0.015%.

The TPS79325YZQR linear voltage regulator is ideal for battery operated application such as portable consumer electronics, PDAs, and other handheld devices. Its small 3-lead MSOP package makes it ideal for space-constrained applications, while power MOSFET provides more efficient power delivery.

The TPS79325YZQR linear voltage regulator supports three operating modes. Low dropout mode provides the lowest dropout voltage, making it suitable for applications with limited headroom voltage. In high output current mode, the regulator provides a higher output current while maintaining its low dropout voltage. Finally, in sleep mode, the regulator enters a low power state to preserve battery life. The regulator also has an enable and disable functionality, providing a low current standby mode.

The TPS79325YZQR has an internal over-temperature protection function,the thermal performance is good, and it is not limited by thermoelectric conversion. In addition, the device is designed to be tolerant to transients. Utilizing a power MOSFET provides improved stability under varying loads and helps with noise suppression from its large capacitive load. It also provides improved power efficiency compared to other linear regulators.

In summary, the TPS79325YZQR linear voltage regulator is a small package, low-power, low-dropout linear regulator integrated with a low-side TrenchFET power MOSFET. It is an ideal choice for use in battery operated application such as portable consumer electronics, PDAs, and other handheld devices. The regulator has adjustable output voltage from 0.94V to 2.5V as well as over-temperature protection and improved power efficiency over other linear regulators.
