This device is an excellent choice for use in battery-powered applications, as active terminators for the SCSI bus, and portable computers. The LM1117 features very low quiescent current and very low dropout voltage of 1V at a full load and lower as output current decreases. LM1117 is offered in a 3-pin surface mount package SOT-223, TO-252 & SOT-89. The output capacitor of 10㎌ o r larger is needed for output stability of LM1117 as required by most of the other regulator circuits.

APPLICATION INFORMATION
Maximum Output Current Capability The LM1117 can deliver a continuous current of 1A over the full operating junction temperature range. However, the output current is limited by the re striction of power dissipation which differs from packages. A heat sink may be required depending on the maximum power dissipation and maximum ambient temperature of application. With respect to the applied package, the maximum output current of 1A may be still undeliverable due to the restriction of the power dissipation of LM1117. Under all possible conditions, the junction temperature must be within the range specified under operating conditions. The temperatures over the device are given by: TC = TA + PD X θCA / T J = TC + PD X θJC / T J = TA + PD X θJA where TJ is the junction temperature, T C is the case temperature, T A is the ambient temperature, P D is the total power dissipation of the device, θCA is the thermal resistance of case-to-ambient, θJC is the thermal resistance of junction-to-case, and θJA is the thermal resistance of junction to ambient. The total power dissipation of the device is given by: PD = PIN – POUT = (VIN X IIN)–(VOUT X IOUT) = (VIN X (IOUT+IGND)) – (VOUT X IOUT) = (VIN - VOUT) X IOUT + VIN X IGND where IGND is the operating ground current of t he device which is specified at the Electrical Characteristics. The maximum allowable temperature rise (T Rmax) depends on the maximum ambient temperature (T Amax) of the application, and the maximum allowable junction temperature (TJmax): TRmax = TJmax – TAmax The maximum allowable value for junction-to-ambient thermal resistance, θJA, can be calculated using the formula: θ JA = TRmax / PD = (TJmax – TAmax) / PD LM1117 is available in SOT223, TO252 and SOT89 package s. The thermal resistance depends on amount of copper area or heat sink, and on air flow. If the maximum allowable value of θJA calculated above is over 137°C/W for SOT-223 package, over 105 °C/W for TO252 package, over 315 °C/W for SOT-89 package, no heat sink is needed since the package c an dissipate enough heat to satisfy thes e requirements. If the value for allowable θJA falls near or below these limits, a heat sink or proper area of copper plane is required. In summary, the absolute maximum ratings of thermal resistances are as follow: Absolute Maximum Ratings of Thermal Resistance Characteristic Symbol Rating Unit Thermal Resistance Junction-To-Ambient / SOT-223 θJA-SOT-223 137 °C/W Thermal Resistance Junction-To-Ambient / TO-252 θJA-TO-252 105 °C/W Thermal Resistance Junction-To-Ambient / SOT-89 θJA-SOT-89 315 °C/W No heat sink / No air flow / No adjacent heat source / 0.066 inch2 copper area.
