The CLM2810 is a low power, positive voltage regulator. The
device has been designed to provide an output current of 1A
while complying with SCSI-II specifications with a fixed output
voltage of 2.85V. Applications include battery-powered and
portable computers. The device has a low quiescent current
while providing 1.2V drop-out voltage at a full load. Product is
available as an adjustable LDO or fixed 2.85V, 3.0V, 3.3V and
5.0V output voltages.

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 input 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.
