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.

*For packages with exposed thermal pads, such as QFN, PowerPAD, and PowerFLEX,

θJP is defined as the thermal resistance between the die

junction and the bottom of the exposed pad.

NOTE 1: Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient

temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
