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 lowvoltage 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. 1 • • • • • Fixed 1.8-V, 2.5-V, and 3.3-V Outputs ±1% Maximum Output Voltage Tolerance at TJ = 25°C 500-mV Maximum Dropout Voltage at 500 mA (3.3-V Option) ±2% Output Voltage Variation Across Load and Temperature Internal Overcurrent Limiting Internal Thermal-Overload Protection Internal Overvoltage Protection 2 Applications • • • • • Electronic Points of Sale Medical, Health, and Fitness Applications Printers Appliances and White Goods TV Set-Top Boxes Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) TLV2217-xxPW TSSOP (20) 6.50 mm × 4.40 mm TLV2217-xxKVU TO-252 (2) 6.04 mm × 6.15 mm TLV2217-xxKCS TO-220 (3) 10.16 mm × 9.15 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.

The device is available in 1.8-V, 2.5-V, and 3.3-V options. All internal circuitry is designed to operate down to 0.5-V input-to-output differential, with the minimum input voltage of 3 V for all voltage options. The TLV2217 device is designed to be stable with tantalum and aluminum electrolytic output capacitors having an ESR between 0.4 Ω and 2 Ω. The TLV2217 device is characterized for operation over the virtual junction temperature range of 0°C to 125°C. 7.2 Functional Block Diagram INPUT OUTPUT R1 + Over Temp & Over Current Protection R2 1.25 V GND Copyright © 2016, Texas Instruments Incorporated 7.3 Feature Description 7.3.1 Overload Block Current limiting and overtemperature shutdown protects against overload by turning off the PNP pass element. 7.4 Device Functional Modes 7.4.1 Operation With Low Input Voltage The TLV2217 device requires 0.5-V headroom (VI – VO) to operate in regulation. With less headroom, the device may drop out and OUTPUT voltage is INPUT voltage minus dropout voltage. 7.4.2 Operation at Light Loads The load or feedback must consume the minimum bias current defined in Electrical Characteristics: TLV2217-33 for regulation, or the output may be too high. 7.4.3 Operation in Self Protection When an overload occurs, the device shuts down the output stage or reduce the output current to prevent device damage. The device automatically resets from the overload. The output may be reduced or alternate between on and off until the overload is removed.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information The TLV2217 is a low-dropout linear regulator and can be used as a fixed output voltage supply for a wide variety of applications up to 500 mA. The TLV2217 has multiple output voltage options including 1.8 V, 2.5 V, and 3.3 V. The TLV2217 requires a minimum of 3 V or (VO(max) + 0.5 V) input to ensure regulation and is characterized for operation over the virtual junction temperature range of 0°C to 125°C. 8.2 Typical Application TLV2217-33 INPUT OUTPUT VO = 3.3 V GND 3.8 V 0.1 µF 22 µF Copyright © 2016, Texas Instruments Incorporated Figure 2. Typical Application Schematic 8.2.1 Design Requirements The input voltage must be high enough so that there is enough headroom for the output to regulate. This specification is defined as the dropout voltage in the Electrical Characteristics: TLV2217-33. A 0.1-µF capacitor must be place on the input to stabilize the input supply, especially if the TLV2217 is not placed near the source of supply. Output capacitor selection is critical for regulator stability. Larger COUT values benefit the regulator by improving transient response and loop stability. This device is designed to be stable with tantalum and aluminum electrolytic output capacitors having an ESR between 0.4 Ω and 2 Ω. See Compensation-Capacitor Selection Information for additional details regarding capacitor selection. 8.2.2 Detailed Design Procedure 8.2.2.1 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. Figure 3 and Figure 4 can be used to establish the capacitance value and ESR range for the best regulator performance. 8 Submit Documentation Feedback Copyright © 1992–2016, Texas Instruments Incorporated Product Folder Links: TLV2217 TLV2217 www.ti.com SLVS067M – MARCH 1992 – REVISED NOVEMBER 2016 Typical Application (continued) 0.04 CL = 22 µF CI = 0.1 µF TJ = 25°C Not Recommended Potential Instability Not Recommended Potential Instability Recommended Minimum ESR 1000 µF 0.035 0.03 2.2 2 1.8 1.6 1.4 Region of Best Stability 0.025 Maximum ESR Boundary CL ESR − Equivalent Series Resistance − Ω 3 2.8 2.6 2.4 400 µF 0.02 1.2 0.015 1 0.8 Minimum ESR Boundary 200 µF 100 mF 0.01 0.6 0.4 0.005 0.2 0 0 0.1 0.2 0.4 0.3 0.5 0 22 µF 10 µF 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 1/ESR IL − Load Current − A Figure 3. TLV2217 ESR of Output Capacitor vs Load Current Figure 4. TLV2217 Stability vs ESR 8.2.2.2 High Start-up Current Due to the structure of the TLV2217, a high peak current is required on start-up. See Figure 5 for the input current characteristic. NOTE When the TLV2217 is starting up, it has to overcome the peak current to start regulating at the output. Due to the peak current required for the TLV2217, a resistor connected in series with the input is not recommended, as the I*R drop across the resistor may cause the input voltage to drop below the required headroom for the device. 8.2.3 Application Curves 200 180 Input Current [mA] 160 140 120 100 80 60 40 20 0 0 1 2 3 4 5 6 7 8 Input Voltage [V] 9 10 11 12 D001 Figure 5.

Input and output bypass capacitors must be placed as close to the device pins as possible. The output capacitor must have a specified ESR in the range defined by Figure 4. Additionally, the ground pin and thermal tab must be well connected to a ground plane to aid in thermal dissipation. 10.2 Layout Example GND INPUT OUT GND Figure 6.
