LM1117S-3.3 Description

Short technical summary and product information.

The LM1117S-3.3 is a positive fixed output voltage regulator manufactured by HTC Korea. It is designed to provide a stable 3.3V output with a maximum output current of 1A. This LDO (Low Dropout) regulator features a low dropout voltage of 1.3V at 1A, making it efficient for various power management applications.

The device operates with a maximum input voltage of 12V and has a typical Power Supply Rejection Ratio (PSRR) of 75dB at 120Hz, helping to filter out input voltage ripple. The operating temperature range is from -40°C to 125°C (TJ).

Packaged in a SOT-223 surface-mount case, the LM1117S-3.3 is suitable for applications where space is a constraint. Its fixed output configuration simplifies circuit design, requiring minimal external components. This regulator is a reliable choice for embedded systems, consumer electronics, and industrial control applications requiring a consistent 3.3V power supply.
