FAN2560 — 350mA Low-VIN LDO with Fast Transient Response www.DataSheet4U.com February 2008 FAN2560 350mA Low-VIN LDO with Fast Transient Response Features ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ 55µA Typical Quiescent Current Up to 350mA Output Current 2.9V to 5.5V Bias Supply Voltage VOUT+0.1V to 5.5V Power Input Supply Voltage Fixed Voltage Options: 1.3V and 1.5V Thermal Shutdown Protection (TSD) Input Under-Voltage Lockout (UVLO) Short-Circuit Current Protection (SCP) 5-bump 0.96 x 1.33mm WLCSP Description The FAN2560 is a linear low-dropout (LDO) regulator with a split-supply architecture. Separate bias and supply inputs allow bias to be taken directly from the battery, while the input is taken from a lower preregulated source. This allows a smaller differential voltage between input and output, which provides greater efficiency over a wider VBAT range. The FAN2560 is available in a fixed-voltage output, 5-bump, WLCSP package.
