Technical content

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

Applications

„ Post regulation for switching DC/DC con- verter „ High efficiency linear regulator „ Battery charger „ Battery powered instrumentation „ Motherboard 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 cur- rent protection circuits to prevent it from being dam- aged by abnormal operating conditions. The G1117 is available in TO-252, SOT-223 and TO-92 packages. A minimum of 10 μF tantalum elec- trolytic 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. For the G1117 in SOT-223 package; θJA is 116°C/W (See recommend minimum footprint). 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.

With two external resistors. It can be for- mulated as: R 2 VOUT = 1.25V x (1+ R1 ) + IADJ x R2 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 cur- rent 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 af- fected. 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.
