The ABLIC Inc. S-1721 series is a dual positive fixed output linear voltage regulator designed for applications requiring stable and efficient power delivery. This SNT-6A packaged device, part number S-1721B1818-I6T1U, provides two 1.8V outputs, each capable of delivering up to 150mA. With a low quiescent current of 1 µA and a maximum input current of 45 µA, it is suitable for battery-powered and energy-conscious designs. The regulator features an enable pin for power sequencing and over-current protection for enhanced reliability. It exhibits excellent power supply rejection ratio (PSRR) of 75dB at 1kHz for both outputs. The voltage dropout is a mere 0.35V at 100mA per output, allowing for operation with lower input voltages up to 6.5V. This component is widely utilized in portable electronics, industrial equipment, and automotive subsystems. Supplied in a Tape & Reel (TR) package.
