The S-1142BA4I-E6T1U is a linear voltage regulator that belongs to the PMIC (Power Management Integrated Circuit) category. This voltage regulator is a low-dropout regulator that is capable of precise adjustment and can operate normally even at low input voltages and low loads. It is designed to have features and performance suitable for digital consumer applications.

This voltage regulator is mainly composed of the Positive Voltage Regulator, loop compensation circuit and Shutdown logic circuit. The Positive Voltage Regulator circuit contains a reference voltage which is stable and not affected by temperature changes, a precision amplifier and a pass transistor. The loop compensation circuit is mainly composed of an error amplifier, a duty cycle control circuit and a feedback circuit. The Shutdown logic circuit is mainly composed of a Power Good signal processing circuit and a comparator.

The working principle of the S-1142BA4I-E6T1U voltage regulator is the same as that for standard linear voltage regulators. The input voltage is stepped down in either the form of a resistor divider or current limiting circuit. The output voltage of the linear voltage regulator is then regulated, which is regulated by the error amplifier in the loop compensation circuit. The output of this error amplifier is fed back to the reference voltage circuit to adjust and stabilize the output voltage as needed. When the output voltage reaches the set value, the reference voltage is regulated and the loop remains stable in the balanced state.

The S-1142BA4I-E6T1U voltage regulator is mainly used in digital consumer electronic applications, such as tablets and mobile phones. Its features and performance make it suitable for use in the digital consumer market. This voltage regulator is also suitable for use in applications such as domestic electricity and power supply systems, automotive power converters and battery chargers. It is also used in display systems, such as LCD and LED displays for home appliances, projectors, and television.

The S-1142BA4I-E6T1U voltage regulator is a highly efficient regulator with a low dropout. It has an adjustable output voltage which can range from 0.7V to 3.6V. The device also has a low standby current of only 200µA. It is capable of stable operation up to an operating temperature range of -40°C to +125°C.
