The S-1121B32MC-N2RTFG is an integrated linear voltage regulator, classified as PMIC – Voltage Regulators – Linear. It is manufactured by Fujitsu and is part of the Fujitsu UQ2 series of Voltage Regulators.

The S-1121B32MC-N2RTFG is a single-output, medium-current voltage regulator. It is rated at up to 32V output voltage and 1.2A output current, with a low dropout voltage of 2.6V. Additionally, it has a range of features and protection circuitry such as overload protection, output discharge, output short-circuit protection, and UVLO protection.

The S-1121B32MC-N2RTFG is intended for use in a wide range of voltage regulation applications. This device can be used in automotive, industrial, and consumer electronic systems. Its wide input voltage range from 6V to 35V allows for the device to be used in both low and high voltage systems. Its low output voltage drops also make it suitable for battery-powered systems.

The S-1121B32MC-N2RTFG utilizes a linear voltage regulation approach to provide a constant output voltage. This is accomplished by monitoring the output voltage and adjusting the output current accordingly. The current is adjusted by turning the pass element on and off in order to source or sink current. When the output voltage rises above the target voltage, the pass element is turned off, thus reducing the output current. Similarly, when the output voltage drops, the pass element is turned on, thus increasing the output current. This cycle is continuously repeated in order to maintain a constant output voltage.

In order to further increase reliability, the S-1121B32MC-N2RTFG also includes various protection features. These include output overload protection, output discharge protection, output short-circuit protection, and UVLO protection. The overload protection monitors the output current and will disable the output if the current exceeds the maximum specified limit. The output discharge protection prevents the output from shorting to ground during a sudden drop in input voltage. The output short-circuit protection also protects against a short between the output and ground. The UVLO protection prevents the device from operating if the input voltage is too low.

In summary, the S-1121B32MC-N2RTFG is an integrated linear voltage regulator from Fujitsu UQ2 series. It is rated at up to 32V output voltage and 1.2A output current with a low dropout voltage of 2.6V. The device can be used in a wide range of voltage regulation applications, including automotive, industrial, and consumer electronics systems. Additionally, it includes a range of protection features such as output overload protection, output discharge protection, output short-circuit protection, and UVLO protection.
