3.3V 800mA Low-Dropout Linear Voltage Regulator IC for Embedded and Industrial Power Designs (SOT-223 Package)
The LD1117S33TR is a fixed 3.3V low-dropout (LDO) linear voltage regulator IC designed to deliver stable output with load current capability up to 800mA. It is widely used to generate a regulated 3.3V rail from 5V or higher DC inputs in microcontroller boards, communication modules, and digital logic systems. The low-dropout architecture ensures reliable regulation even when the input voltage is only slightly above the output voltage, making it suitable for efficient DC supply designs.
Housed in a SOT-223 surface-mount package, this regulator offers good thermal performance for medium-current applications when used with proper PCB copper area. It is commonly implemented in embedded systems, development boards, IoT devices, and industrial control circuits that require a dependable 3.3V power supply.
