The HG7150MK-1/TR with SOT-89-3 is an electronic component manufactured by HGSEMI. It is a linear voltage regulator (LDO) that is designed to reduce an input voltage to a lower, more stable output voltage. It is commonly used in applications such as powering LED lights, motor driver circuits, and microcontrollers. This component is RoHS compliant and provides excellent transient response and low noise with a 3-pin SOT-89 footprint. The output current rating is 150mA with an operating input voltage range of 3.2V to 18V, and it features a wide operating temperature range (-40°C to +85°C). The HG7150MK-1/TR with SOT-89-3 is an ideal choice for low power, cost-effective, and reliable LDO solutions.
