Use the LDO ADP1716ARMZ-3.3-R7 linear regulator from Analog Devices to maintain a constant output voltage. It has an overall accuracy of ±2 %. Its typical dropout voltage at current is 0.05@100mA|0.25@500mA V. This voltage regulation device's single output can produce a current up to 0.5 A. The best way to provide power to your application is by using this, which needs a voltage of at least 2.5 V and no higher than 5.5 V. With a fixed output that has a voltage of 3.3 V, this is power management at its best. Users like the load regulation of 0.002%/mA(Typ) and line regulation of 0.15%/V. Tape and reel packaging will encase this product during shipment, in order to ensure safe delivery and enable quick mounting of components. Its polarity is positive. The maximum dropout voltage is 0.1@100mA|0.3@500mA V. This voltage regulation device has an operating temperature range of -40 °C to 125 °C.
