Detailed Description for TLV1117-18CDCYR
Product Overview
The Texas Instruments TLV1117-18CDCYR is a single-output linear voltage regulator that provides a fixed positive 1.8V output at up to 800mA. It accepts input voltages up to 15V and has a maximum dropout voltage of 1.3V at 800mA. The device includes over-current and over-temperature protection and operates from 0°C to 125°C. It is packaged in a surface-mount SOT-223-4 package, also identified as TO-261-4 or TO-261AA. The regulator can be used for board-level power conversion where a fixed 1.8V rail is needed from a higher DC supply, and its 10mA quiescent current and 75dB PSRR at 120Hz are relevant to input noise rejection.
Key Features
- Fixed positive 1.8V output from a single regulator channel.
- 800mA output current rating.
- Maximum input voltage of 15V.
- Maximum dropout voltage of 1.3V at 800mA.
- 10mA quiescent current.
- 75dB PSRR at 120Hz.
- Over-current and over-temperature protection.
- 0°C to 125°C operating temperature range.
- Surface-mount SOT-223-4 package (TO-261-4, TO-261AA).
Applications
- Generating a fixed 1.8V supply rail for digital logic devices on a printed circuit board.
- Regulating a 1.8V output from a higher DC bus in embedded control hardware where the input remains within 15V and dropout margin is available.
- Providing a protected single-rail 1.8V source for surface-mount assemblies that require over-current and over-temperature protection.
Design & Procurement Notes
Design and procurement should focus on confirming that the available input voltage provides the required dropout margin above 1.8V while remaining at or below 15V. The 10mA quiescent current and 800mA output rating should be considered in power and thermal budgets, while the 0°C to 125°C range supports placement within surface-mount assemblies. The fixed 1.8V output removes external resistor adjustment from the regulator circuit, and the SOT-223-4 package should be matched to the chosen board layout. The exact manufacturer part number TLV1117-18CDCYR should be used when specifying the device to ensure the correct output voltage and package are selected.
