Power Dissipation ...................................... Internally Limited

Lead Temperature (soldering, 5 seconds) .................. 260°C

Storage Temperature Range ...................... -65°C to +150°C

NOTES:

Note 1: Output temperature coefficient is defined as the worst case voltage change divided by the total temperature range.

Note 2: Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below its nominal value measured at 1V differential at

very low values of programmed output voltage, the minimum input supply voltage of 2V ( 2.3V over temperature) must be taken into account.

Note 3: Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied excluding load or line regulation effect.

Operating Junction Temperature Range ..... -40°C to +125°C

Input Supply Voltage ..................................................... +20V

ESD Rating .............................................................. 2kV min
