FAN1539B / FAN1540B 1A/1.3A, LDO with Low Quiescent Current June 2007 FAN1539B / FAN1540B 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 Thermal Shutdown Current Limit Disk Drive Circuits Desktop Computers Laptops, Notebook Computers General-Purpose, Three-Terminal Regulators The FAN1539B / FAN1540B 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 that 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 FAN1539B / FAN1540B is available in the thermally enhanced 3x3mm 6-lead MLP package.
