1.8V 1A Positive Voltage Regulator
Features
General Description
Output current in excess of 1A
The SS8026 positive 1.8V voltage regulator features
the ability to source 1A of output current. The typical
quiescent current is 0.48mA.
Output voltage accuracy +2.5%/-2%
Quiescent current typically 480µA
Internal short-circuit current-limit
Internal over-temperature protection
Familiar regulator features such as over-temperature
and over-current protection circuits are provided to
prevent it from being damaged by abnormal operating
conditions.
Applications

Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Conditions
are conditions under which the device functions but the specifications might not be guaranteed. For guaran-
teed specifications and test conditions see the Electrical Characteristics.
The maximum power dissipation is a function of the maximum junction temperature, TJmax , total thermal re-
sistance, qJA, and ambient temperature TA. The maximum allowable power dissipation at any ambient tem-
perature is Tjmax-TA / qJA. If this dissipation is exceeded, the die temperature will rise above 150°C and the IC will
go into thermal shutdown. For the SS8026 in SOT 89 package, qJA is 250°C/W. For the SS8026 in SOT 223
package, qJA is 156°C/W; in TO 252 package, qJA is 125°C/W. (See recommend minimum footprint). The safe
operation in SOT 89, SOT 223, TO 252 package, can be seen in “Typical Performance Characteristics” (Safe
Operating Area).
Note 1:
Note2:
Note3: Low duty pulse techniques are used during test to maintain junction temperatures as close to ambient as
possible.
Note4: The output capacitor should be a tantalum or aluminum type.

Definitions
Dropout Voltage
Load Regulation
The input/output voltage differential at which the regu-
lator output no longer maintains regulation against fur-
ther reductions in input voltage. Measured when the
output drops 100mV below its nominal value. Dropout
voltage is affected by junction temperature, load cur-
rent and minimum input supply requirements.
The change in output voltage for a change in load cur-
rent at constant chip temperature. The measurement is
made under conditions of low dissipation or by using
pulse techniques such that the average chip temperature
is not significantly affected.
Maximum Power Dissipation
Line Regulation
The maximum total device dissipation under which the
regulator will operate within specifications.
The change in output voltage for a change in input volt-
age. The measurement is made under conditions of
low dissipation or by using pulse techniques such that
the average chip temperature is not significantly affected.
Quiescent Bias Current
Current which is used to operate the regulator chip and
is not delivered to the load.
