Feb 03, 2015 Ver. 07 Like most regulators, the IL1117C regulates the output by comparing the output voltage to an internally gen- erated reference voltage. On the adjustable version as shown in Fig.4, the V REF is available externally as 1.25V between VOUT and ADJ. The voltage ratio formed by R1 and R2 should be set to conduct 10mA (min u- mum output load). The output voltage is given by the following equation: Vo=Vref(1+R2/R1)+Iadj*R2 On fixed versions of IL1117C, the voltage divider is provided internal- ly. Figure 4. Basic Adjustable Regulator The adjust terminal can be bypassed to ground with a bypass capacitor (CADJ) to improve ripple rejection. The R1 is the resistor between the output and the adjust pin. Its value is normally in the range of 100- 200Ω. For example, with R1 = 124Ωand fRIPPLE = 120Hz, the CADJ should be 11μF. IL1117C requires a capacitor from VOUT to GND to provide compensation feedback to the internal gain stage. Note: The ESR is typically 1.0 Ω. The output capacitor does not have a theoretical upper limit and increasing its value will increase stability. COUT = 100μF or more is typical for high current regulator design. ground pins can be connected to low side of the load.
Figure 5. Best Load Regulation Using Adjustable Output Regulator IL1117C is protected against overload conditions. Current protection is triggered at typically 1.6A. and ambient. It includes junction-tocase, case-to-heat-sink interface, and heat sink thermal resistance itself. case of the device must be electrically isolated, a thermally conductive spacer is recommended.
