Detailed Description for TLV1117-33CDCYR
Product Overview
The Texas Instruments TLV1117-33CDCYR is a positive fixed-output linear voltage regulator intended for single-rail 3.3V supply conversion. The device accepts an input voltage up to 15V and delivers up to 800mA, with a specified maximum dropout of 1.3V at 800mA. It is supplied in a surface-mount SOT-223-4 package, identified as TO-261-4 or TO-261AA, and is specified for operation over a 0°C to 125°C temperature range. Built-in over-current and over-temperature protection are included, and the regulator provides 75dB PSRR at 120Hz.
Key Features
- Positive fixed 3.3V output from a single regulator channel.
- Input voltage capability up to 15V with 800mA output current.
- Maximum dropout voltage specified as 1.3V at 800mA.
- Quiescent current of 10 mA and power-supply rejection ratio of 75dB at 120Hz.
- Protection features include over-current and over-temperature conditions.
- Surface-mount SOT-223-4 package with TO-261-4 or TO-261AA case identification.
Applications
- Regulated 3.3V rail for logic and mixed-signal board circuits.
- Step-down conversion from higher-voltage single-supply rails to a fixed 3.3V output.
- Local linear regulation for moderate-current peripheral and sensor subsystems.
- Noise-sensitive analog or digital board sections where 75dB PSRR at 120Hz is useful.
- Surface-mount power regulation in equipment operating between 0°C and 125°C.
Design & Procurement Notes
When selecting this regulator, verify that the available input voltage remains below 15V and provides sufficient headroom for the 1.3V maximum dropout at 800mA. The 10 mA quiescent current should be considered in power budgeting, especially when the load is light or the regulator is continuously powered. Thermal design must account for dissipation in the SOT-223-4 package, since the difference between input and 3.3V output multiplied by load current produces heat. The specified 0°C to 125°C operating range and surface-mount package support standard board assembly, while over-current and over-temperature protection can reduce risk under fault conditions.
