Global Mixed-mode Technology Inc. G1084-XX 5A Low-Dropout Linear Regulator 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 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 circuits 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 220µF tantalum electrolytic capacitor is required at the output to improve the transient response and stability.

Operating Conditions are conditions under which the device functions but the specifications might not be guaranteed. For guaranteed specifications and test conditions see the Electrical Characteristics. Note2: 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 Tjmax-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 current and minimum input supply requirements. Line Regulation The change in output voltage for a change in input voltage. The measurement is made under conditions of low dissipation or by using pulse techniques such that average chip temperature is not significantly affected. Ver: 0.9 Jun 14, 2007 Load Regulation The change in output voltage for a change in load current at constant chip temperature. The measurement is made under conditions of low dissipation or by using pulse techniques such that average chip temperature 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. TEL: 886-3-5788833 http://www.gmt.com.tw 2 Global Mixed-mode Technology Inc.
