Nisshinbo Micro Devices Inc. Voltage Regulators - Linear R1172D181D-TR-FE

The R1172D181D-TR-FE is a CMOS-based linear voltage regulator IC designed for applications requiring a low dropout voltage and a maximum output current of 1A. It operates within an input voltage range of 1.4V to 6.0V and can provide output voltages from 0.8V to 5.0V in 0.1V increments. The device features a typical dropout voltage of 0.32V at 1.5V output and 1A load, making it suitable for low-voltage applications. This regulator includes several built-in protection features such as thermal shutdown, current limit, and an inrush current limit circuit. The standby current is low, typically 0.1OºA, which is beneficial for battery-powered devices. The output voltage accuracy is ¬±2.0%, with a temperature-drift coefficient of ¬±100ppm/¬8C, ensuring stable performance across varying temperatures. The R1172D181D-TR-FE is available in a compact HSON-6 package, allowing for high-density mounting on PCBs. It is suitable for use in local power sources for portable communication devices, cameras, and home appliances.
