The device features extremely low dropout voltages, high PSRR, low output noise, low quiescent current, and enable-input to reduce supply currents to less than 1μA when the regulator is turned off. Enable Sequence ETA5055 is enabled when all below conditions happen. Otherwise, ETA5055 is in standby mode.  EN pin voltage above Logic High level  VIN is higher than Under-Voltage-Lock-Out Level.  Junction Temperature is not at Over-Temperature Protection level. Once all above conditions happen, ETA5055 first enable internal 2.4V regulator, before enable BIAS, and BANDGAP. Finally, when internal bias ready, ETA5055 enable LDO core. ETA5055 is completed forced in shutdown mode when EN pin is at below LOGIC_LOW that supply current is less than 1μA. Otherwise, part only shutdown the VOUT while other circuit still in operation. Once ETA5055 is in shutdown conditions, Output is discharged by 90Ω resistor. Output Current Limit and Foldback Current Limit ETA5055 family features an internal current limit. In normal operation, the ETA5055 limits output current to approximately 800mA. When current limiting engages, the output voltage scales back linearly until the over current condition ends. In case output is in hard short conditions, ETA5055 also features an internal foldback limit that reduces the output current limit to a lower level, 400mA, then reduce power dissipation ratings of the package. Over-Temperature Protection Thermal protection disables the output when the junction temperature rises to approximately 150° C, allowing the device to cool down. When the junction temperature cools to approximately 120° C, the output circuitry is again enabled. Depending on power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit may cycle on and off. This cycling limits regulator dissipation, protecting the device from damage as a result of overheating. www.etasolution.com ETA5055 Rev2.1 7 Empower, Transcend, Achieve! ETA5055 PACKAGE OUTLINE Package: SOT23-5 ETA5055VXXXDS2F www.etasolution.com ETA5055 Rev2.1 8 Empower, Transcend, Achieve! ETA5055 PACKAGE OUTLINE Package: CSP-4 ETA5055VXXXDCNE RECOMMENDED LAND PATTERN www.etasolution.com ETA5055 Rev2.1 9 Empower, Transcend, Achieve! ETA5055 Package: DFN1x1-4 From assembly house1: ETA5055VXXXDF1E 3 4 2 1 From assembly house2: ETA5055VXXXDD1E www.etasolution.com ETA5055 Rev2.1 10 Empower, Transcend, Achieve! ETA5055 Package: DFN2x2-6 ETA5055VXXXDD2G www.etasolution.com ETA5055 Rev2.1 11 Empower, Transcend, Achieve! ETA5055 AVAILABLE PART NUMBER Part Description Part Number Package Mark Pcs/Reel 1.2V With Discharge CSP-4 ETA5055V120DCNE CSP-4 B 10000 1.8V With Discharge CSP-4 ETA5055V180DCNE CSP-4 D 10000 2.8V With Discharge CSP-4 ETA5055V280DCNE CSP-4 F 10000 3.3V With Discharge CSP-4 ETA5055V330DCNE CSP-4 K 10000 1.1V with Discharge DFN1x1-4 ETA5055V110DD1E DFN1x1-4 ev 10000 1.2V with Discharge DFN1x1-4 ETA5055V120DD1E DFN1x1-4 YW CD 10000 YW 1.5V with Discharge DFN1x1-4 ETA5055V150DD1E DFN1x1-4 CN 10000 YW 1.8V with Discharge DFN1x1-4 ETA5055V180DD1E DFN1x1-4 CX 10000 YW 2.8V with Discharge DFN1x1-4 ETA5055V280DD1E DFN1x1-4 C8 10000 YW 2.9V with Discharge DFN1x1-4 ETA5055V290DD1E DFN1x1-4 3.0V with Discharge DFN1x1-4 ETA5055V300DD1E DFN1x1-4 eq 10000 YW Cy 10000 YW 3.3V with Discharge DFN1x1-4 ETA5055V330DD1E DFN1x1-4 Ck 10000 YW 1.1V with Discharge DFN1x1-4 ETA5055V110DF1E DFN1x1-4 ev 10000 YW 1.2V with Discharge DFN1x1-4 ETA5055V120DF1E DFN1x1-4 CD 10000 YW 1.5V with Discharge DFN1x1-4 ETA5055V150DF1E DFN1x1-4 1.8V with Discharge DFN1x1-4 ETA5055V180DF1E DFN1x1-4 CN 10000 YW CX 10000 YW 2.8V with Discharge DFN1x1-4 ETA5055V280DF1E DFN1x1-4 C8 10000 YW 2.9V with Discharge DFN1x1-4 ETA5055V290DF1E DFN1x1-4 eq 10000 YW 3.0V with Discharge DFN1x1-4 ETA5055V300DF1E DFN1x1-4 Cy 10000 YW 3.3V with Discharge DFN1x1-4 ETA5055V330DF1E DFN1x1-4 Ck 10000 1.1V with Discharge SOT23-5 ETA5055V110DS2F SOT23-5 evYW 3000 1.2V with Discharge SOT23-5 ETA5055V120DS2F SOT23-5 WDYW 3000 1.5V with Discharge SOT23-5 ETA5055V150DS2F SOT23-5 WNYW 3000 1.8V with Discharge SOT23-5 ETA5055V180DS2F SOT23-5 WXYW 3000 2.5V with Discharge SOT23-5 ETA5055V250DS2F SOT23-5 WJ∣YW 3000 YW www.etasolution.com ETA5055 Rev2.1 12 Empower, Transcend, Achieve! ETA5055 Part Description Part Number Package Mark Pcs/Reel 2.8V with Discharge SOT23-5 ETA5055V280DS2F SOT23-5 W8YW 3000 2.9V with Discharge SOT23-5 ETA5055V290DS2F SOT23-5 WS∣YW 3000 3.0V with Discharge SOT23-5 ETA5055V300DS2F SOT23-5 WyYW 3000 3.3V with Discharge SOT23-5 ETA5055V330DS2F SOT23-5 WkYW 3000 1.1V with Discharge DFN2X2-6 ETA5055V110DD2G DFN2X2-6 evYW 3000 1.2V with Discharge DFN2X2-6 ETA5055V120DD2G DFN2X2-6 CDYW 3000 1.5V with Discharge DFN2X2-6 ETA5055V150DD2G DFN2X2-6 CNYW 3000 1.8V with Discharge DFN2X2-6 ETA5055V180DD2G DFN2X2-6 CXYW 3000 2.5V with Discharge DFN2X2-6 ETA5055V250DD2G DFN2X2-6 CJ∣YW 3000 2.8V with Discharge DFN2X2-6 ETA5055V280DD2G DFN2X2-6 C8YW 3000 3.0V with Discharge DFN2X2-6 ETA5055V300DD2G DFN2X2-6 CyYW 3000 3.3V with Discharge DFN2X2-6 ETA5055V330DD2G DFN2X2-6 CkYW 3000 TAPE AND REEL INFORMATION Device ETA5055VXXXDCNE Package Type CSP-4 Reel Pins SPQ Reel Diameter Width W1 (mm) (mm) A0 B0 K0 P1 W Pin1 (mm) (mm) (mm) (mm) (mm) Quadrant 4 10000 178 9.5 0.45 0.45 0.34 2 8 Q1 ETA5055VXXXDD1E DFN1x1-4 4 10000 180 9.5 1.16 1.16 0.5 2 8 Q1 ETA5055VXXXDF1E DFN1x1-4 4 10000 180 9.5 1.16 1.16 0.5 2 8 Q1 ETA5055VXXXDD2G DFN2x2-6 6 3000 180 9.5 2.3 2.3 1.1 4 8 Q1 ETA5055VXXXDS2F 5 3000 180 9.5 3.17 3.23 1.37 4 8 Q3 SOT23-5 www.etasolution.com ETA5055 Rev2.1 13 Empower, Transcend, Achieve!
