Use the LDO MCP1824T-1802E/DC linear regulator from Microchip Technology to maintain a constant output voltage. It has an overall accuracy of ±2.5 %. Its typical dropout voltage at current is 0.2@300mA V. This voltage regulation device"s single output can produce a current up to 0.3(Min) A. With a small input voltage of 2.1 V and a max of 6 V, this will supply sufficient power to your circuit. With a fixed output that has a voltage of 1.8 V, this is power management at its best. Your circuit has the capability to produce a constant current at its output by using a load regulation of 0.5%(Typ) and line regulation of 0.05%/V(Typ). This component will be shipped in tape and reel packaging to allow for effective mounting and safe delivery. This voltage regulation device has an operating temperature range of -40 °C to 125 °C. Its polarity is positive. The maximum dropout voltage is 0.32@300mA V.
