The HT7905ARMZ is a Linear Voltage Regulator (LDO) with ROHS certification by HTCSEMI. This device is designed to provide stable voltage outputs to sensitive circuitry by regulating the input voltage to a specified level. The package is a TO-252 PowerPAK SMT surface mount package, making it suitable for applications that require small devices. The device has a maximum output current of 2.8A, voltage drop of 0.5V, a temperature operating range of -40 to +125°C, and requires an external divider/capacitor. It is capable of supplying a wide range of output voltages from 0.8V to 2.75V. The device also features a low noise voltage output and a low dropout voltage, making it suitable for high-performance, microprocessor-based systems.
