Additional Details

The R1161N151B-TR-FE LDO regulator is optimized for use in portable and battery-powered devices where power efficiency is paramount. Its low dropout voltage allows it to maintain a stable output voltage even when the input voltage is close to the output voltage. The low quiescent current minimizes power consumption during standby or idle modes, extending battery life. The overcurrent, short-circuit, and thermal shutdown protection features enhance system reliability by preventing damage from fault conditions. The small package size helps to reduce board space requirements in compact devices. The output voltage is fixed at 1.5V.
