8V Description The FAN1539/FAN1540 series of high current LDO (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 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 l...
