IRU1010-33CY is a three terminal adjustable voltage regulator, which belongs to the category of PMIC – Voltage Regulators – Linear. It is commonly used in various applications related to voltage regulation and current-limiting. This regulator features adjustable output regulation and current-limiting protection for short circuit conditions. It offers high output current, up to ±1A. As a linear regulator, it also offers high accuracy, low noise, and fast response time.

The IRU1010-33CY achieves adjustable voltage output control from a positive input voltage range of 4.5V to 20V. It has three input/output terminals, i.e. the positive input voltage, negative power, and adjustable voltage output. It also has short-circuit protection and thermal shut-down protection to prevent self-heating, thus it is highly reliable. Furthermore, the device is capable of providing high output current of ±1A.

In terms of working principle, the IRU1010-33CY regulator operates according to an open loop control concept. The regulator works as a linear amplifier, where the output voltage is adjusted by controlling the input/output voltage ratio. The output voltage is compared with a reference voltage, and the difference is amplified by the internal op-amp. This amplified signal is then used to control the transistor base current, and hence the output voltage is regulated. The output voltage can be adjusted by changing the voltage applying to the control terminal.

The IRU1010-33CY regulator is mainly suitable for applications where high output current is required and input voltage can vary. It can be used in various applications such as power supply, portable device charging, LED backlighting, battery charging/discharging circuits, industrial equipment power supply, and battery powered systems. Additionally, its high accuracy and fast response time makes it ideal for applications where precise regulation is needed. Moreover, the device is suitable for battery-powered applications such as mobile phones and laptop computers, since it has low quiescent current and features short-circuit protection that helps protect the battery.

IRU1010-33CY is a valuable addition to the linear voltage regulator market. It can provide high output current, adjustable output voltage and current-limiting protection for short circuit conditions. In addition to being suitable for many applications, its fast response time, low noise, and high accuracy make it a desirable choice for applications where precise regulation is needed.
