Specifications:

The SP6213EC5-3-3/TR has a fixed output voltage of 3.3V. It can deliver a maximum output current of 300mA. The input voltage range is typically 2.5V to 6V. The dropout voltage is typically 150mV at 300mA. It is stable with output capacitors as small as 1µF. It features short-circuit and over-temperature protection. The package is a SOT23-5.

The SP6213EC5-3-3/TR's low dropout voltage allows it to operate efficiently even when the input voltage is close to the output voltage. The short-circuit and over-temperature protection features enhance its reliability. The small SOT23-5 package makes it well-suited for portable devices with limited board space. Its compatibility with ceramic capacitors reduces the overall cost and size of the power supply circuit.
