AP1501-33K5L-13

Voltage Regulators - DC DC Switching Regulators Overview

The AP1501-33K5L-13 is a monolithic step-down DC/DC converter manufactured by Diodes Incorporated. It operates with an input voltage range of 4.5 V to 40 V and provides a fixed 3.3 V output at up to 3 A load current without requiring external driver components. The device utilizes a buck topology with a switching frequency of 150 kHz. It is housed in a TO-220-5 package designed for through-hole mounting. The unit supports a shutdown function and operates within a temperature range of -20 °C to +85 °C.
