FAN2559MP18X

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The FAN2559MP18X is a fixed positive linear voltage regulator manufactured by onsemi, formerly Fairchild Semiconductor. It provides a fixed output voltage of 1.8V with a maximum continuous output current of 180mA. The device operates within an input voltage range of 2.7V to 5.5V and features a low dropout characteristic. It is housed in a compact 6-DFN (2x2mm) surface-mount package with an exposed pad for thermal dissipation.
