It offers excellent transient response and output voltage noise and is designed for low noise and high ripple rejection. This makes it suitable for powering wireless systems, such as WLAN and Bluetooth radios, as well as automotive systems and consumer electronics. It also offers protection from overvoltage, overcurrent, and reverse voltage.

The S-1112B30MC-L6PTFG can also be used in portable device powering solutions, such as the latest tablets, phones, and gaming systems. Its wide input voltage range, fast transient response, and low output voltage noise makes it an ideal design choice for applications that require high output current and stability.

Working Principle

The S-1112B30MC-L6PTFG is a highly adjustable low dropout linear regulator that features a built-in constant-current circuit to ensure stability. In operation, a voltage is applied to the input of the LDO, and the regulator compares it to the regulated output voltage. If the output voltage falls below its preset level, the regulator increases its output current to bring the output voltage back up to the set point. If the output voltage rises above its preset level, the regulator decreases its output current to bring the output voltage back down to the set point.

For improved ripple rejection and noise performance, the S-1112B30MC-L6PTFG has a high slew rate of up to 500μA/μs and a low output impedance of up to 0.5Ω. This ensures fast transient responses and high output voltage accuracy. The LDO also features short circuit, overvoltage and overcurrent protection, making it suitable for use in a wide range of applications.

Conclusion

The S-1112B30MC-L6PTFG is an ultra-low quiescent current, low-noise low-dropout (LDO) linear regulator that supports up to two amps of load current. It enables efficient and low-noise power management designs, is ideal for battery-powered applications, and offers excellent transient response and output voltage noise. This regulator is suitable for use in a variety of consumer and industrial applications, including portable devices, laptop computers, medical equipment, consumer audio systems, automotive systems, and more.
