Nisshinbo Micro Devices Inc. Voltage Regulators - Linear, Low Drop Out (LDO) Regulators R1171S331B-E2-FE

The R1171S331B-E2-FE is a linear voltage regulator from the R1171x series by Lingto Electronic Limited, designed to provide a fixed output voltage of 3.3V with a maximum output current of 1.5A. It operates within an input voltage range of 2.1V to 6.0V and features a low dropout voltage of approximately 0.09V at 300mA output current. The device is characterized by low supply current (typical 130µA) and ultra-low standby current (typical 0.1µA), which contribute to extended battery life in portable applications. The regulator includes built-in protection features such as a current limit circuit and thermal shutdown, enhancing reliability in various applications. It is suitable for local power sources in notebook PCs, portable appliances, and home electronics. The R1171S331B-E2-FE is available in a high wattage HSOP-6J package, allowing for high-density mounting on PCBs. The output voltage accuracy is ±2.0%, and it supports ceramic capacitors for phase compensation, making it versatile for different circuit designs.
