The S-1170B30UC-OTPTFG is a linear voltage regulator from the PMIC - Voltage Regulators - Linear family. It is designed to provide a regulated output voltage for any load type, from direct DC to multiple capacitive elements and load currents up to 1A. It also provides an output voltage accuracy within +/-1.5% over temperature range, excellent line and load regulation, and low output noise. The S-1170B30UC-OTPTFG is ideal for consumer applications such as mobile phones, digital cameras and PDAs, as well as industrial and automotive applications.

The S-1170B30UC-OTPTFG is constructed with an N-channel P-type metal-oxide-semiconductor field-effect transistor (MOSFET) as its internal transistor, which is the main contribution to its low input and output voltages. It is also equipped with a programmable over-temperature protection switch (OTPTFG) which can be used to protect the output voltage from sudden over-temperature changes.

The S-1170B30UC-OTPTFG provides various protections such as over-temperature, overvoltage, and overcurrent protection, making it an ideal choice for applications with a potentially high risk of surges or current shortages. It is also configured in an industry-standard TO-220 package, making it easy to install and convenient to maintain. The S-1170B30UC-OTPTFG also features a low quiescent current, excellent power supply rejection ratio (PSRR), and a wide operating temperature range.

The S-1170B30UC-OTPTFG is designed to provide a regulated output voltage for a variety of applications. Its main application area is for powering mobile phones, digital cameras, PDAs, and other portable electronic devices. It can also be used for automotive and industrial applications, such as providing a stable voltage source for motors, pumps, and lighting circuits.

The working principle behind the S-1170B30UC-OTPTFG is simple. When the input voltage exceeds the output voltage, the internal transistor is switched ON and starts to draw current. This causes the voltage to drop across the 470?F electrolytic capacitor and reduce the output voltage. Once the differential voltage between the input and the output decreases, the reverse is true and the output voltage rises back to its original value. At the same time, the OTPTFG switch is activated and cuts off the current abruptly if the output voltage or temperature exceeds predetermined limits.

Overall, the S-1170B30UC-OTPTFG is a reliable, robust, and efficient linear voltage regulator that is capable of meeting the demands of a wide variety of applications. It is suitable for applications with a potentiall high risk of surges or current shortages and features an industry-standard TO-220 package for easy installation. It also provides excellent line and load regulation, low output noise, and a wide operating temperature range.
