Features

„ Available in 1.5V, 1.8V, 2.5V, 3.3V version „ TO-252,TO-263 and TO-263T package „ Internal short circuit current limiting „ Internal over temperature protection „ Output current 5A

Applications

„ Post regulation for switching DC/DC con- verter „ High efficiency linear regulator „ Battery powered instrumentation „ Motherboard General Description The G1084-XX is a low dropout linear regulator with a dropout of 1.3V at 5A of load current. It is available in three fixed voltages: 1.5V, 1.8V, 2.5V and 3.3V. Refer to the G1084 for the adjustable version. The G1084-XX provides over temperature and over current protection circ uits to prevent it from being damaged by abnormal operating conditions. The G1084-XX is available in TO-252, TO-263 and TO-263T packages. A minimum of 220 µF tanta- lum electrolytic capacitor is required at the output to improve the transient response and stability.

Operating C onditions are conditions under which the device functions but the specifications might not be guaranteed. For guaranteed specifications and test conditions see the Electrical Characteristics. Note 2: The maximum power dissipation is a function of the maximum junction temperature, TJmax ; total thermal resistance, θJA, and ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is T jmax-TA / θJA. If this dissipation is exceeded, the die temperature will rise above 150°C and IC will go into thermal shutdown. Note3: Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible. Note4: The type of output capacitor should be tantalum or aluminum. Definitions Dropout Voltage The input/output Voltage differential at which the regulator output no longer maintains regulation against further reductions in input voltage. Measured when the output drops 2% below its nominal value. Dropout voltage is affected by junction temperature, load cur- rent and minimum input supply requirements. Line Regulation 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 av- erage chip temperature is not significantly affected. Load Regulation The change in output voltage for a change in load current at constant chip temperature. The measure- ment is made under conditions of low dissipation or by using pulse techniques such that average chip tem- perature is not significantly affected. Maximum Power Dissipation The maximum total device dissipation for which the regulator will operate within specifications. Quiescent Bias Current Current which is used to operate the regulator chip and is not delivered to the load.
