Frequently Asked Questions
What is the output voltage and maximum output current of TLV1117-33CDCY?
The TLV1117-33CDCY provides a fixed 3.3V output voltage with a maximum continuous output current of 800mA. It maintains regulation as long as the input voltage stays between 4.7V and 15V and the input-output differential exceeds the dropout voltage of typically 1.2V.
What is the dropout voltage of TLV1117-33CDCY and how does it affect design?
The typical dropout voltage of TLV1117-33CDCY is 1.2V (1.3V maximum at full load). This means the input supply must be at least 4.5V to maintain the 3.3V regulated output. Low dropout ensures efficient operation in battery-powered designs where input voltage is close to the desired output.
What protection features does TLV1117-33CDCY include?
TLV1117-33CDCY integrates internal current limiting and thermal overload protection. Current limiting prevents damage during output short-circuit events, while thermal shutdown automatically disables the device if junction temperature becomes excessive, resuming normal operation once the device cools down.
What package does TLV1117-33CDCY use and what are typical applications?
TLV1117-33CDCY comes in a SOT-223 (3-pin) surface-mount package, which offers excellent thermal performance due to its large exposed pad. Typical applications include powering 3.3V rails for microcontrollers, FPGAs, Wi-Fi modules, sensors, and other digital or analog ICs in consumer electronics and industrial systems.
