Detailed Description for TLV1117-33CDCY
Product Overview
The Texas Instruments TLV1117-33CDCY is a positive fixed-output linear voltage regulator that provides a single 3.3 V output. It accepts an input voltage up to 15 V and delivers up to 800 mA. The maximum dropout voltage is 1.3 V at 800 mA, and the device includes over-current and over-temperature protection. It is supplied in a SOT-223-4 surface-mount package, also referenced as TO-261-4 or TO-261AA. The regulator has 10 mA quiescent current, 75 dB PSRR at 120 Hz, and an operating temperature range of 0°C to 125°C.
Key Features
- Positive fixed 3.3 V output with one regulator and 800 mA output current.
- Input voltage up to 15 V with 1.3 V maximum dropout at 800 mA.
- Quiescent current of 10 mA and PSRR of 75 dB at 120 Hz.
- Over-current and over-temperature protection features.
- Surface-mount SOT-223-4 package, also identified as TO-261-4 or TO-261AA.
- Operating temperature range from 0°C to 125°C.
Applications
- 3.3 V regulated supply for logic, sensors, microcontrollers, and digital subsystems.
- Board-level conversion from a higher DC input to a fixed 3.3 V rail.
- Powering peripheral circuits that require up to 800 mA from a single linear regulator output.
- Surface-mount power stages where over-current and over-temperature protection are required.
Design & Procurement Notes
For layout planning, note that the device is a SOT-223-4 surface-mount package and operates from 0°C to 125°C, so thermal management should be considered when the regulator approaches 800 mA output. The 1.3 V maximum dropout at 800 mA means the input rail should remain sufficiently above 3.3 V under load to maintain regulation. The 10 mA quiescent current and 75 dB PSRR at 120 Hz are relevant for power budgeting and input-noise-sensitive designs. Over-current and over-temperature protection are included, while the maximum input voltage is 15 V and the fixed output is 3.3 V.
