ETA5055 FUNCTIONAL BLOCK DIAGRAM VIN VOUT 90Ω EN REGULATOR OFF ILIMS BIAS BANDGAP RESISTOR NETWORK GND THERMAL MONITOR RES 5pF FUNCTIONAL DESCRIPTION The ETA5055 family of LDO regulators has been optimized for application in noise-sensitive equipment. 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!
