(www.ecmos.com.tw) Page 3 of 10 2007/09/17 EC50117 1A Positive Voltage Regulators Typical Application Application Hints Like any linear voltage regulator, EC50117 requires external capacitors to ensure stability. The external capacitors must be carefully selected to ensure performance. Input Capacitor An input capacitor of at least 10µF is required. Ceramic or Tantalum can be used. The value can be increase without upper limit. Output Capacitor An output capacitor is required for stability. It must be placed no more than 1 cm away from the VOUT pin, and connected directly between VOUT and GND pins. The minimum value is 22µF but may be increase without limit. Thermal Considerations It is important that the thermal limit of the package is not exceeded. The EC50117 has built-in thermal protection. When the thermal limit is exceeded, the IC will enter protection, and VOUT will be pulled to ground. The power dissipation for a given application can be calculated as following: PD = IOUT * [VIN – VOUT] E-CMOS Corp. (www.ecmos.com.tw) Page 4 of 10 2007/09/17 EC50117 1A Positive Volt.
