The output current capability of the regulator is in excess of 800 mA, with a typical dropout voltage of less than 1.0 V. Internal protective features include current and thermal limiting. The MC33269 is not internally compensated and thus requires an external output capacitor for stability. The capacitor should be at least 10 F with an equivalent series resistance (ESR) of less than 10 over the anticipated operating temperature range. With economical electrolytic capacitors, cold temperature operation can pose a problem. As temperature decreases, the capacitance also decreases and the ESR increases, which could cause the circuit to oscillate. Solid tantalum capacitors may be a better choice if small size is a requirement. Also capacitance and ESR of a solid tantalum capacitor is more stable over temperature. An input bypass capacitor is recommended to improve transient response or if the regulator is connected to the supply input Figure 10. Typical Fixed Output Application Vin MC33269-XX Cin Gnd An input capacitor is not necessary for stability, however it will improve the overall performance. V out CAdj* CO 10 F Vout filter with long wire lengths. This will reduce the circuit's sensitivity to the input line impedance at high frequencies. A 0.33 F or larger tantalum, mylar, ceramic, or other capacitor having low internal impedance at high frequencies should be chosen. The bypass capacitor should be mounted with shortest possible lead or track length directly across the regulator's input terminals. Applications should be tested over all operating conditions to insure stability. Internal thermal limiting circuitry is provided to protect the integrated circuit in the event that the maximum junction temperature is exceeded. When activated, typically at 170C, the output is disabled. There is no hysteresis built into the thermal limiting circuit. As a result, if the device is overheating, the output will appear to be oscillating. This feature is provided to prevent catastrophic failures from accidental device overheating. It is not intended to be used as a substitute for proper heatsinking. Figure 11. Typical Adjustable Output Application Vin MC33269 Cin Adj R2 R1 CO 10 F Vout + 1.25 1 ) R2 ) IAdj R2 R1 Figure 12. Current Regulator Vin MC33269 Cin Adj I out CO 10 F RS Iout *CAdj is optional, however it will improve the ripple rejection. The MC34269 develops a 1.25 V reference voltage between the output and the adjust terminal. Resistor R1, operates with constant current to flow through it and resistor R2. This current should be set such that the Adjust Pin current causes negligible drop across resistor R2. The total current with minimum load should be greater than 8.0 mA. + 1.25 R S Figure 13. Battery Backed-Up Power Supply Vout MC33269-XX Cin Gnd Figure 14. Digitally Controlled Voltage Regulator Vin MC33269 Cin Adj R2 CO 10 F R1 Vout Vin MC33269-XX Cin Gnd The Schottky diode in series with the ground leg of the upper regulator shifts its output voltage higher by the forward voltage drop of the diode. This will cause the lower device to remain off until the input voltage is removed. R2 sets the maximum output voltage. Each transistor reduces the output voltage when turned on.
