Quiescent current is 100µA. Dropout voltage is a maximum of 1.3V at 800mA load. Protection features include over-current and over-temperature shutdown. ## Package and assembly – SOT-223-4 The SOT-223-4 package is a surface-mount part with a large tab for heat sinking. The package is also available in Tape & Reel or Cut Tape.","metaTitle":"TI TLV1117LV28DCYR LDO Regulator, 2.8V Fixed, 1A, SOT-223-4","metaDescription":"Texas Instruments TLV1117LV28DCYR positive fixed LDO regulator: 2.8V output, 1A, 75dB PSRR, -40°C to 125°C, SOT-223-4.
