Tab Contour Optional Within Dim. The AS features very low quiescent current and very low dropout voltage of 1.

The output capacitance could increase in size to above the minimum datashret. Refer To Applicable Symbol List. The actual thermal resistance can be determined with experimentation.


The AS features the internal thermal limiting to protect the device during overload conditions. Limits in Boldface apply over the full operating temperature range. L is the Termal Length for Soldering.

ALPHA makes no guarantee for any errors that appear in this document. Circuit Layout, Thermal Experiments. This device is an excellent choice for use in battery-powered applications, as active terminators for the SCSI bus, and portable computers. Thermal regulation is dayasheet as the change in output voltage at a time T after a change in power dissipation is applied.

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. The SOT recommended soldering method are as follows: Refer to table 1 for the results of the experiment. AS is available as an adjustable or fixed 2. as111

Substrate Layout for SOT excessive thermal gradients on the package. ALPHA Semiconductor products are not authorized for use as critical components in life support devices or systems, nuclear power, aircraft, or space equipment without express written approval from the president of ALPHA Semiconductor.

These limits are subject to change upon the completion of the full characterization over the specified temperature dtasheet supply voltage ranges. The information provided here is believed to be reliable and accurate, however ALPHA assumes no responsibility for its use.

The value of ESR can vary from the type of capacitor used in the applications. ALPHA makes no representation that the circuit descriptions herein will not infringe upon existing patent rights. AS power dissipation is calculated as follows: The thermal interaction from other components in the application can effect the thermal resistance of the AS
