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.

COMPENSATION-CAPACITOR SELECTION INFORMATION  
The TLV2217 is a low-dropout regulator. This means that the capacitance loading is important to the performance  
of the regulator because it is a vital part of the control loop. The capacitor value and the equivalent series resistance  
(ESR) both affect the control loop and must be defined for the load range and the temperature range. Figures 1 and 2  
can be used to establish the capacitance value and ESR range for the best regulator performance.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in  
a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.

Eco Plan  
-
The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS  
&
no Sb/Br)  
-
please check  
http://www.ti.com/productcontent for the latest availability information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame  
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)  
(3)  
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
