description/ordering information (continued)
The TLV2217 family of low-dropout regulators offers a variety of fixed-voltage options that offer a maximum
continuous input voltage of 16 V, making them more versatile than CMOS regulators. Utilizing a pnp pass
element, these regulators are capable of sourcing 500 mA of current, with a specified maximum dropout of
500 mV (3.3-V and 2.5-V options), making these regulators ideal for low-voltage applications. Additionally, the
TLV2217 regulators offer very tight output accuracy of ±2% across operating load and temperature ranges.
Other convenient features the regulators provide are internal overcurrent limiting, thermal-overload protection,
and overvoltage protection. The TLV2217 family of regulators is available in fixed voltages of 1.8 V, 2.5 V, and
3.3 V.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
