| FAN1539/FAN1540 1A/1.3A, LDO with Low Quiescent Current November 2005 FAN1539/FAN1540 1A/1.3A, LDO with Low Quiescent Current • Very Low Ground Current IGND = 1mA • Excellent Line Regulation • Excellent Load Regulation • Very Low Transient Overshoot • Stable with low ESR Output Capacitor ESR = • Thermal Shutdown • Current Limit • Output Options 3.3V and 1.8V • Disk Drive Circuits • Desktop Computers • Laptop, Notebook Computers • General Purpose Three Terminal Regulator The FAN1539/FAN1540 series of high current LDOs 1.0A and 1.3A has been developed for portable applications where low quiescent current is an important requirement. The device features excellent line and load transient response which does not exceed 10% of nominal output value for full operating temperature range even during power ON cycle and short circuit removal. Internally trimmed, temperature compensated bandgap reference guarantees accuracy for full range of input voltage, output current and temperature. Included on the chip are accurate current limit and thermal shutdown protection. Device stability is achieved with only two external low ESR ceramic capacitors. The FAN1539/FAN1540 is available in thermally enhanced 3x3mm 6-lead MLP, 5x6mm 8-lead MLP and 3-lead TO-252 packages. The 5x6mm MLP package version features a separate Kelvin sense pin for high precision applications.
