TP70918DRVT is a 3.3V/5V micro-power voltage regulator with low quiescent current, high output accuracy and high ripple rejection. It can operate over a wide input supply voltage range of 1.6 V to 5.5 V, and is laterally compensated to offer excellent load and line regulation. Little additional input and output capacitors are required making the TPS70918DRVT suitable for applications such as low power micro controllers, MP3 players and digital cameras.The TPS70918DRVT is made using a proprietary CMOS process that enables the integration of multiple voltage regulators on a single monolithic die. The device features a high output-drive capability (up to 100 mA) which is typically achieved with 5 V supplies. The regulator operates from an input voltage of up to 5.5 V and can produce a regulated voltage of either 3.3 V or 5 V, depending upon the selection of the resistor values, if required.Due to the low quiescent current, the TPS70918DRVT is suitable for battery powered system applications. It can provide the regulated output voltage in spite of input supply and load current excursions. The stability of the output voltage is ensured with a small output capacitor of 47 uF. With an output current of 500mA, it provides more than enough energy to the load even during transients.The TPS70918DRVT has a typical quiescent current of 0.08mA and a maximum of 0.25mA. The regulator is available in a 5-lead SOT-23 package (standard Pb-free) and can be provided as a discrete component. The device also features input voltage monitor and over-current and thermal protection.The TPS70918DRVT linear voltage regulator is an ideal choice for applications such as low power micro controllers, MP3 players and digital cameras. It has a wide input voltage range of 1.6 V to 5.5 V, a low quiescent current, high output accuracy, high ripple rejection and high output drive capability. It offers a low cost, simple and efficient solution for a variety of power management needs.

Working Principle

The TPS70918DRVT linear voltage regulator operates by using a voltage comparator with an internal reference voltage. The input voltage is compared to the reference voltage and, if it is greater than the reference voltage, the comparator makes an output that turns on the FET transistor and allows current to flow from the output to the ground through it. This reduces the output voltage to the desired level.

The output voltage is regulated by a feedback loop. The output voltage is monitored and fed back to the input of the comparator so that the output voltage stays at a constant level.

The TPS70918DRVT is made using a proprietary CMOS process that enables the integration of multiple voltage regulators on a single monolithic die. It is available in a 5-lead SOT-23 package (standard Pb-free). The device also features input voltage monitor, over-current and thermal protection. Due to the low quiescent current, the TPS70918DRVT is suitable for battery powered system applications.

Conclusion

The TPS70918DRVT linear voltage regulator is an ideal choice for low power applications such as micro controllers, MP3 players and digital cameras. It has a wide input voltage range, low quiescent current, high output accuracy, and high ripple rejection. It provides a low cost, simple and efficient solution for a variety of power management needs.
