The S-1335M1C-M5T1U3 is an ultra-small, low-drop-out (LDO) voltage regulator equipped with output current limiting and short circuit protection. It is part of a PMIC (power management integrated circuit) in the voltage regulators family, falling within the category of linear voltage regulators. The S-1335M1C-M5T1U3 features accurate current limit and low output impedance for reliable power supply up to 250 KHz. Furthermore, the S-1335M1C-M5T1U3 offers high power supply rejection ratio (PSRR) from 10Hz up to 1 KHz bandwidth frequency range.

The S-1335M1C-M5T1U3 provides a variety of applications, such as automatic thermal shutoff providing extended output current limit, shutdown control and output drive. This voltage regulator is commonly found in homes, businesses, industrial plants, office equipment, computer peripheral devices, audio amplifiers and other applications.

The S-1335M1C-M5T1U3 includes several integrated components, such as the gate resistor, startup current limiting, adjustable output voltage (with internal 1.2V reference), thermal shutdown and short circuit protection. In addition, the S-1335M1C-M5T1U3 has two critical packages: one is the dual-inline-package (DIP) and the other is the surface-mount-package (SOP). The DIP option comes with an 8-pin beam lead, dual-in-line package that provides reliable operation up to 30V and the SOP option incorporates a 9-pin SOIC to provide output current regulation, low-power and thermal shutdown features.

The S-1335M1C-M5T1U3 provides a high degree of output voltage stability, typically with a maximum dropout of about 0.4V for a 3.3V output voltage. It also offers fast load transients and good rejection of power supply disturbances. The suggested capacitive loading on the output is quite small, typically around 0.1µF decoupling capacitors that provide stable operation even with a capacitor that is not rated for the high temperature range.

The S-1335M1C-M5T1U3 works on the principle of regulation by resistive voltage division. The output voltage is determined by the R1 resistor. To achieve a desired output voltage, the R1 resistor is adjusted to an appropriate value. When the power supply current is increased, the resistance of the R1 resistor is increased and the output voltage is lowered. Similarly, when the power supply current is decreased, the screen of the output voltage is increased.

The S-1335M1C-M5T1U3 also features several additional features that make it highly robust, such as transient protection, reverse-bias protection and its low quiescent current. It is generally designed for battery-powered systems, where a low quiescent current is beneficial. It also offers exceptional power line noise rejection, reducing the output ripple due to external power source disturbances.

In conclusion, the S-1335M1C-M5T1U3 is an industry-leading, linear voltage regulator that offers steady output voltage, low drop out voltage, high PSRR, excellent load and line transient response, precise current limitation and overload protection. It is commonly used in a wide variety of applications, including automotive, consumer electronics, industrial, computer and telecommunication products. The S-1335M1C-M5T1U3 is suitable for both switching and linear voltage regulators. It is suitable for battery-powered devices due to its low quiescent current and offers reverse-bias protection.
