SIP21106DR-45-E3

The SIP21106DR-45-E3 is a linear voltage regulator IC manufactured by Sumida Corporation. It is a 3.3V/45mA voltage regulator in a single-in-line (SIP) package with a fixed output voltage of 3.3V and a maximum output current of 45mA. The SIP21106DR-45-E3 has an operating temperature range of -20° to +85°C, and is RoHS compliant. The SIP21106DR-45-E3 is designed for both input and output short-circuit protection.

The SIP21106DR-45-E3 is widely used in various fields such as automotive, industrial, and medical applications due to its wide operating voltage range, low power consumption and robustness. It is widely used in battery chargers, power supplies, lighting devices and other low-power electronic systems. It is also capable of providing a stable output voltage even in the presence of varying input voltage and current or transient inputs.

SIP21106DR-45-E3 works on the principle of linear regulation. The integrated circuit contains an internal voltage reference, an error amplifier and an output driver stage. The error amplifier compares the input voltage to the reference voltage, controls the output current, and provides the feedback necessary for regulation. The output driver is a power transistor that provides current to the output load. The SIP21106DR-45-E3 uses a unique external compensation circuitry, which enables fast transient response without requiring external components.

The SIP21106DR-45-E3 also provides protection against overheating and overcurrent. It is equipped with thermal shutdown protection for overheating and overcurrent protection for output short circuit conditions. These protective features help to ensure the long-term viability and reliability of the system.
