AME1117 n Application Description 1. Output Voltage Adjustment Like most regulators, the AME1117 regulates the output by comparing the output voltage to an internally generated reference voltage. On the adjustable version, the VREF is available externally as 1.25V between VOUT and ADJ. The voltage ratio formed by R1 and R2 should be set to conduct 10mA (minimum output load). The output voltage is given by the following equation: R2 VOUT = VREF ( 1 + ) + IADJ x R2 R1 On fixed versions of AME1117, the voltage divider is provided internally. 3. Current Limit Protection AME1117 is protected against overload conditions. Current protection is triggered at typically 1.5A. 4. Stability and Load Regulation AME1117 requires a capacitor from VOUT to GND to provide compensation feedback to the internal gain stage. This is to ensure stability at the output terminal. Typically, a 10F tantalum or 50F aluminum electrolytic is sufficient. (Note: It is important that the ESR for this capacitor does not exceed 0.5.) 1A Low Dropout Positive Voltage Regulator VIN IN ADJ C1 IADJ 55A OUT VREF VOUT The output capacitor does not have a theoretical upper limit and increasing its value will increase stability. COUT = 100F or more is typical for high current regulator design. For the adjustable version, the best load regulation is accomplished when the top of the resistor divider (R1) is connected directly to the output pin of the AME1117. When so connected, RP is not multiplied by the divider ratio. For fixed output versions, the top of R1 is internally connected to the output. The ground pin can be connected to the low side of the load in order to eliminate ground loop errors. RP Parasitic Line Resistance IN ADJ R1 (Connect R1 to case) RL OUT R1 R2 VOUT = VREF (1+R2 ) + IADJ x R2 R1 2. Thermal Protection AME1117 has thermal protection which limits junction temperature to 150oC. However, device functionality is only guaranteed to a maximum junction temperature of +125oC. The power dissipation and junction temperature for AME1117 is given by PD = (VIN - VOUT) x IOUT TJUNCTION = TAMBIENT + ( PD x JA) Note: T JUNCTION must not exceed 125oC VIN R2 Connect R2 to load 10 Rev.S.02 AME, Inc. AME1117 5. Thermal Consideration The AME1117 series contain thermal limiting circuitry designed to protect itself from over-temperature conditions. Even for normal load conditions, maximum junction temperature ratings must not be exceeded. As mentioned in thermal protection section, we need to consider all sources of thermal resistance between junction and ambient. It includes junction-to-case, case-to-heat-sink interface and heat sink thermal resistance itself. Junction-to-case thermal resistance is specified from the IC junction to the bottom of the case directly below the die. Proper mounting is required to ensure the best possible thermal flow from this area of the package to the heat sink. The case of all devices in this product series is electrically connected to the output. Therefore, if the case of the device must be electrically isolated, a thermally conductive spacer is recommended. 1A Low Dropout Positive Voltage Regulator Rev.S.02 11 AME, Inc.
