The S-1170B15UC-OTATFG is a 15V, low quiescent voltage drop, linear voltage regulator with a maximum rated output current of 1A. It is part of the S-1170 series of voltage regulators from Toshiba. It is optimized for battery-powered and highly noise-sensitive applications. The S-1170B15UC-OTATFG has an input range of 4.5V to 15V, allowing for efficient conversion of higher voltage levels to a desired output level of up to 300mA, with minimum power dissipation.

The S-1170B15UC-OTATFG operational characteristics are based upon the principles of an open loop voltage regulator. The device has three main components: an analog circuit, a digital, or pulse-width modulation (PWM) controller and a feedback loop. The S-1170B15UC-OTATFG utilizes a combination of analog and digital signals to control its output voltage with a tight accuracy of +-2%.

The S-1170B15UC-OTATFG acts as a linear regulator by monitoring the voltage across its output and uses the feedback loop to adjust the current being supplied by the output transistor so that the output voltage stays within the desired range. When the output voltage reaches its desired level, the linear regulator will reduce the voltage supply and keep it at the desired level. The S-1170B15UC-OTATFG also offers a wide operating temperature range of -40°C to +85°C.

The S-1170B15UC-OTATFG is an ideal choice for applications that are looking for precise and reliable power management. The device is well suited for use in battery-powered, sensitive electronics, and in automotive applications. Its low quiescent voltage drop makes it particularly suitable for applications such as load sharing, as well as for applications that require low current consumption and high accuracy. The S-1170B15UC-OTATFG is also useful in providing reliable power management for computer peripherals such as USB, Wi-Fi, and general purpose embedded systems.

The S-1170B15UC-OTATFG features an active Low-Dropout (LDO) regulator and is designed with low supply current consumption in mind. Its output voltage range is adjustable with a single external resistor. The output voltage accuracy is maintained over a wide range of temperatures, ensuring reliable operation in harsh environments. The S-1170B15UC-OTATFG also offers a short-circuit protection and over-temperature protection, adding to its overall reliability.

In conclusion, the S-1170B15UC-OTATFG is an ideal voltage regulator for applications that require low supply current consumption and high accuracy, such as load sharing and battery-powered electronics. The device offers a wide operating temperature range, low quiescent voltage drop, and active low-dropout (LDO) regulator, making it suitable for use in automotive and computer peripherals. It is a reliable, highly accurate, and easy to use voltage regulator.
