The HG7133M3-1/TR is a Linear Voltage Regulator (LDO) in a SOT-23-3 Surface Mount Device (SMD) package, made by HGSEMI. This RoHS-compliant regulator can provide up to 3A of continuous output current and has an input voltage range of 2.7V to 6.0V. It has a dropout voltage of 0.25V at 2A and is designed to have a low quiescent current, making it very power-efficient. The HG7133M3-1/TR also features a TTL shutdown control, enabling it to be easily connected to control circuitry. The low operating voltage makes it suitable for battery-powered applications such as mobile phones, tablets, and other portable electronic devices.
