The S-1132B49-I6T2G is an ultra-low input voltage linear voltage regulator. The main features that make this voltage regulator so attractive in its field are the wide input voltage range, very low quiescent current, high PSRR and fast transient response, load regulation and a shutdown mode. It is particularly suitable for applications where a very low-noise source is required.

The S-1132B49-I6T2G voltage regulator functions as a shunt regulator, controlling output voltage by regulating a feedback element at an input compared to a reference voltage. The reference voltage is produced from the internal bandgap current source. The regulator uses an Error Amplifier that compares the voltage on the feedback element with the reference voltage to control the output. This permits the output voltage to be precisely regulated. Additional features are included to optimize performance and maintain stability. The output voltage is adjustable by connecting a resistor divider network to the adjustable pin.

The S-1132B49-I6T2G ultra-low input voltage linear regulator has many applications and is highly suitable for portable products. It is widely used in mobile phones, portable navigators, PDAs, GPS receivers, portable medical devices, and other electronic devices. Due to its low noise, high PSRR and fast transient response, this voltage regulator is ideal for applications where a very low-noise source is needed such as audio and recording devices. The adjustable output feature allows this linear regulator to be used in a broad range of applications. It can also be used in post-regulation for switch mode power supplies, where high PSRR and low output voltage noise is important.

The S-1132B49-I6T2G is also widely used in a variety of automotive and industrial applications. Its wide input voltage range, excellent transient response and stability make it well suited for different kinds of motor controls, low-side polarity detection, current-limited power supplies, and power-on reset circuits. Thanks to the wide input voltage range and its small footprint, this linear voltage regulator is also used in industrial machinery and other high power systems with extreme input voltage swings.

In summary, the S-1132B49-I6T2G is an ultra-low input voltage linear voltage regulator that features wide input voltage range, very low quiescent current, high PSRR and fast transient response, load regulation and a shutdown mode. It is an ideal solution for a variety of applications including audio, recording, mobile devices, automotive, and industrial. It is also highly suitable for post-regulation in switch mode power supplies.
