The device features excellent line and load transient response which does not exceed 10% of nomi- nal 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 shut- down 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 and 3-lead TO-252 packages. The 5x6mm MLP package ver- sion features a separate Kelvin sense pin for high preci- sion applications.
