• Description: 500mA CMOS LDO Voltage Regulator
• Manufacturer: SEAWARD [Seaward Electronics Inc.]

Note 1: Exceeding the absolute maximum rating may damage the device.
Note 2: The device is not guaranteed to function outside its operating rating.
Note 3: The maximum allowable power dissipation at any T
Note 4: Output voltage temperature coefficient is the worst case voltage change divided by the total temperature range.
Note 5: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested
Note 6: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its
Note 7: The Cin or Cout should be chosen carefully. Please refer to the Application Hints

for load regulation in the load range from 10mA to 500mA. Changes in output voltage due to heating effects are
covered by the thermal regulation specification.
