WR0332-18A50R is a SOT23-5 Linear Voltage Regulators/LDO manufactured by Wayon. It is RoHS compliant and features an output voltage tolerance of +/- 2%. It has an output current capability of up to 50mA and a wide input range of up to 18V. The LDO also has low dropout characteristics of 0.2V (at full load). The device is protected from over-current, over-temperature, and short-circuit conditions, providing peace of mind that the regulator is protected. This device is an excellent choice for providing stable and consistent output voltage in applications such as voltage level shifting, microcontrollers, RFID systems, and other low power applications.
