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 2.5% 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.
