GS1117-33CTR3

*61117 is an industrial temperature range low dropout linear regulator. The device is optimized for low voltage applications where transient response and minimum input voltage are critical. It provides current limiting and thermal shutdown protection. The circuit incorporates a trimmed bandgap reference to ensure output voltage accuracy within ±1%. On-chip thermal shutdown prevents excessive junction temperature caused by high current combined with elevated ambient temperature. *61117 is available in fixed output voltage versions of 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V, and an ADJ adjustable output voltage version. Fixed versions integrate the adjustment resistors. An adjustable version is also available, allowing output voltage to be set via two external resistors. *61117 is offered in industry-standard SOT223 and TO252-2 power packages.
