Frequently Asked Questions
What is the maximum output current the TLV1117-33CKVU can supply continuously?
The TLV1117-33CKVU is rated for a continuous output current of up to 800 mA. It maintains a fixed 3.3 V output with ±1% accuracy across the load range, making it suitable for powering mid-power digital ICs and mixed-signal subsystems.
What input voltage range is required to keep the TLV1117-33CKVU in regulation?
The TLV1117-33CKVU requires a minimum input voltage of 4.4 V (3.3 V output plus 1.1 V dropout) to remain in regulation. The maximum input voltage is 15 V. Typical designs use a 5 V supply, giving a comfortable 1.7 V headroom above the 1.1 V dropout threshold.
Which package does TLV1117-33CKVU use, and how does it affect thermal management on a PCB?
TLV1117-33CKVU is housed in a SOT-223 package, which provides a large exposed pad for heat dissipation. At 800 mA and a 5 V input, the device dissipates roughly 1.36 W, so an adequate copper area of at least 1 cm² is recommended to keep junction temperature below 125 °C.
When would TLV1117-33CKVU be preferred over a switching regulator for a 3.3 V rail?
TLV1117-33CKVU is preferred when low noise is critical, such as in RF front-ends, analog sensor supplies, or audio circuits. Its LDO architecture eliminates switching noise entirely. At load currents below 500 mA and an input of 5 V, efficiency remains above 66%, which is acceptable in many space- or cost-constrained designs.
