The LD1117D33 is a CMOS low-dropout (LDO) linear voltage regulator designed to deliver highly accurate and low noise output with only a few external components.
LD1117D33 offers low noise and low temperature coefficient of the output voltage. It is also capable of providing up to 100mA of output current with a fairly large input voltage range from 2.2V to 13.2V. The device features an adjustable output voltage ranging from 0.8V to 13.2V as well as a wide range of other features for circuit protection, making it suitable for a variety of general-purpose applications.
LD1117D33 provides superior output voltage accuracy, very low dropout voltage, low noise and high power supply ripple rejection. It is ideal for use in industrial and consumer applications. It also provides excellent line and load regulation. Unlike other linear voltage regulators, it has an extremely low quiescent current which allows it to operate in a very low power state. LD1117D33 is highly efficient and consumes very little power when in operation.
The LD1117D33 is specially designed for high-density applications. The device can easily fit onto a 12mm x 12mm PCB without any extra components. It is very compact and occupies only a small board space. This makes the device suitable for use in space constrained applications. The device is also available in two package options: SOIC-7 and TSSOP-8. This gives users more flexibility when designing the PCB layout.
The LD1117D33 linear voltage regulator working principle is straightforward. It utilizes a transistor to regulate the output voltage. The voltage regulator acts like a current source, and it is set to a specific voltage with the help of a feedback circuit. The feedback circuit measures the output voltage and if it is not within the desired range, it sends a signal to the transistor to increase or decrease current flow and stabilize the output voltage.
The LD1117D33 is designed to provide highly accurate and low noise output with minimum external components. The device can easily fit in medium-density applications and provides excellent line and load regulation. LD1117D33 is suitable for a variety of general-purpose applications where high efficiency, low noise and accurate output voltage are required.
