This device is an excellent choice for use in battery-powered applications, as active terminators for the SCSI bus, and portable computers. The AS features very low quiescent current and very low dropout voltage of 1. AS is available as an adjustable or fixed 2.

Pleasanton, CA Tel: Internally Limited Lead Temp. Limits in Boldface apply over the full operating temperature range. 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 mV below its nominal value measured at 1V differential at very low values of programmed output voltage, the minimum input supply voltage of 2V 2.


Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied. The value of ESR can vary from the type of capacitor used in the applications.

The output capacitance could increase in size to above the minimum value. Circuit Layout, Thermal Datashheet.

Substrate Layout for SOT excessive thermal gradients on the package. The SOT recommended soldering method are as follows: The AS features the internal thermal limiting to protect the device during overload conditions. Refer to table 1 for the results of the experiment. The thermal interaction from other components in the application can effect the thermal resistance of the AS The actual thermal resistance can be determined with experimentation.

AS power dissipation is calculated as follows: Refer To Applicable Symbol List.
