• Manufacturer Part Number: SPX1117T
• Description: 800mA Low Dropout Voltage Regulator
• Manufacturer: Exar Corporation

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
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
