• (1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.

⁽²⁾ The maximum power dissipation is a function of TJ(max) , RθJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(max)–TA) / RθJA. All numbers apply for packages soldered directly into a PCB.

The TLV1117 is a versatile and high-performance, linear regulator with a wide temperature range and tight line and load regulation operation. An output capacitor is required to further improve transient response and stability. For the adjustable option, the ADJ pin can also be bypassed to achieve very-high, ripple-rejection ratios. The TLV1117 is versatile in the device applications, including being used as a post regulator for DC/DC converters, battery chargers, and microprocessor supplies.
