Description
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.
FEATUREs
■ Very Low Ground Current (IGND = 1mA)
■ Excellent Line Regulation
■ Excellent Load Regulation
■ Very Low Transient Overshoot
■ Stable with low ESR Output Capacitor (ESR = 0mΩ)
■ Thermal Shutdown
■ Current Limit
■ Output Options: 3.3V and 1.8V
APPLICATIONs
■ Disk Drive Circuits
■ Desktop Computers
■ Laptop, Notebook Computers
■ General Purpose Three Terminal Regulator
