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 tempera-
ture. Included on the chip are accurate current limit and ther-
mal 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 package and
3-lead TO-252 packages. The 5x6mm MLP package version
features separate Kelvin sense pin for high precision applica-
tions.
