Nisshinbo Micro Devices Inc. Voltage Regulators - Linear R1172S121D-E2-FE

The R1172S121D-E2-FE is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a fixed output voltage with a maximum output current of 1A. It operates within an input voltage range of 1.4V to 6.0V and can output voltages from 0.8V to 5.0V in 0.1V increments. The device features a low dropout voltage, typically 0.32V at 1.5V output and 1A load, making it suitable for applications requiring efficient power management. This regulator includes several built-in protection features such as thermal shutdown, current limit, and an inrush current limit circuit. The typical supply current is 60OºA, with a standby current of only 0.1OºA, enhancing its efficiency in low-power applications. The output voltage accuracy is ±2.0%, and it exhibits good ripple rejection of approximately 70dB at a 2.8V output. The R1172S121D-E2-FE is available in a compact HSOP-6J package, facilitating high-density mounting on PCBs. It is suitable for various applications, including local power sources for portable devices, cameras, and home appliances.
