FAN2564 300mA Low VIN LDO for Digital Applications Features Description               The FAN2564 operates from a minimum input of 1.65V and provides outputs as low as 1.2V. Output current is guaranteed to 300mA, making this regulator ideal for digital loads. Input Voltage 1.65V to 3.6V Guaranteed 300mA Output High Initial Output Voltage Accuracy: ±1% Fixed Output Voltage options from 1.2V to 2.8V Very Low Dropout: 100mV at 300mA 45µA Quiescent Current at No Load Low Output Noise of 100µVRMS Inrush Current Controlled to Less Than 500mA PSRR of 60dB at 1kHz The unique low input voltage capability and very low dropout make this device an ideal post regulator to a synchronous buck regulator. In this configuration, accurate low voltage regulation is provided without the inefficiencies typically related to linear regulators. The enable pin can be used to initiate shutdown mode, where the operating current falls to an extremely low 10nA, typically. The FAN2564 is designed to be stable with spacesaving ceramic capacitors as small as 0402 case size. 100µs Startup Time Stable with Ceramic Capacitors Thermal and Short-Circuit Protection 4-bump WLCSP, 0.5mm Pitch The FAN2564 is available in 4-bump 0.5mm pitch waferlevel chip-scale package (WLCSP) and a 6-lead 2 x 2mm ultra-thin molded leadless package (UMLP). 6-pin 2 x 2mm UMLP Applications     Post Regulator Cell Phones and Smart Phones WLAN, 3G, and 4G Data Cards PMP and MP3 Players Typical Application Circuit Figure 1. © 2007 Fairchild Semiconductor Corporation FAN2564 • Rev. 1.0.2 Typical Application Circuit www.fairchildsemi.com FAN2564 — 300mA Low VIN LDO for Digital Applications April 2011 Part Number Output Voltage(1) FAN2564UC12X 1.2 FAN2564UC13X 1.3 FAN2564UC15X 1.5 FAN2564UC18X 1.8 FAN2564UC25X 2.5 FAN2564UMP12X 1.2 FAN2564UMP13X 1.3 FAN2564UMP15X 1.5 FAN2564UMP18X 1.8 Temperature Range Package Packing Method –40 to 85°C WLCSP-4 0.5mm Pitch Tape and Reel –40 to 85°C 6 Lead UMLP 2 x 2mm Tape and Reel Notes: 1.

The chip is in shut-down mode when EN pin is LOW. For best performance, the die temperature and the power dissipated should be kept at moderate values. The maximum power dissipated can be evaluated based on the following relationship: To enable the chip, the EN pin needs to be raised higher than 0.95V. The output pin starts to charge up to the final voltage. On-chip soft-start circuitry limits the peak inrush current through VIN pin to less than the specified typical value of 500mA, regardless of COUT value and load conditions.  TJ(max)  TA  PD(max)     JA   (1) where TJ(max) is the maximum allowable junction temperature of the die and TA is the ambient operating temperature. θJA is dependent on the surrounding PCB layout and can be improved by providing a heat sink of surrounding copper ground. The startup time increases as VOUT, COUT, and load increases, but meets the specified 100µs under the worst load and VOUT conditions. The addition of backside copper with through-holes, stiffeners, and other enhancements can also aid in reducing θJA. The heat contributed by the dissipation of other devices located nearby must be included in design considerations. Short-Circuit and Thermal Protection The output current is short-circuit protected. When a short-circuit fault occurs, the output current is automatically limited and VOUT drops, depending on the actual short-circuit resistance. Capacitors Selection Short-circuit fault or output overload may cause the die temperature to increase and exceed maximum ratings due to power dissipation. In such cases, depending upon the ambient temperature; VIN, load current, and the junction-to-air thermal resistance (θJA) of the die; the device may enter thermal shutdown. The FAN2564 is stable with a wide range of capacitor values and sizes. For loop stability, a 1µF input capacitor or bigger is recommended. Tolerance, temperature, and voltage coefficients of the capacitor must be considered to ensure effective capacitance stays around 1µF or above. There is no special requirement on its ESR value. When the die temperature exceeds the shutdown limit temperature, the onboard thermal protection disables the output until the temperature drops below its hysteresis value, at which point the output is re-enabled and a new soft-start sequence occurs as described above. An output capacitor with an effective capacitance between 1µF and 10µF is required for loop stability. The ESR value should be within 5 to 100m. 2.2µF or 4.7µF ceramic capacitors are recommended to ensure stability over the full temperature, input, and output voltage range of operation, such as those listed in Table 1.
