G1117

Global Mixed-mode Technology Inc. G1117 1A Adjustable Low-Dropout Linear Regulator Features Available in adjust version Space saving TO-252, SOT-223 and TO-92 package Internal short circuit current limiting Internal over temperature protection Output current in excess of 1A Output current in excess of 100mA with TO-92 package General Description The G1117 is a low dropout linear regulator with a dropout of 1.2V at 800mA of load current and 1.3V at 1A of load current. It is available in an adjustable version, which can set the output from 1.25V to 5V with only two external resistors. The G1117 provides over temperature and over current protection circuits to prevent it from being damaged by abnormal operating conditions. The G1117 is available in TO-252, SOT-223 and TO-92 packages. A minimum of 10μF 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. 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. For the G1117 in SOT-223 package; θJA is 116°C/W (See recommend minimum footprint). Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible. The type of output capacitor should be tantalum or aluminum. Ver: 1.9 Mar 07, 2007 TEL: 886-3-5788833 http://www.gmt.com.tw 2 Global Mixed-mode Technology Inc. Definitions Output Voltage The G1117 provides an adjustable output voltage from 1.25V to 5V. With two external resistors. It can be formulated as: VOUT = 1.25V x (1+ IADJ = 80µA (TYP.) 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 R2 R1 G1117 voltage. The measurement is made under conditions of low dissipation or by using pulse techniques such that average chip temperature is not significantly affected. 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. ) + IADJ x R2 Ver: 1.9 Mar 07, 2007 TEL: 886-3-5788833 http://www.gmt.com.tw 3 Global Mixed-mode Technology Inc.
