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 heat-sinking. Figures 11 through 15 are typical application circuits. 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 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 but greater than 0.2 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. Also capacitance and ESR of a solid tantalum capacitor is more stable over temperature. The use of a low ESR ceramic capacitor placed within close proximity to the output of the device could cause instability. ** An input bypass capacitor is recommended to improve transient response or if the regulator is connected to the Vin MC33269-XX ** Cin Vout Vin Co * 10 F ** Cin Vout MC33269 R1 GND R2 An input capacitor is not necessary for stability, however it will improve the overall performance. CAdj*** Figure 11. Typical Fixed Output Application Vin MC33269 RS Adj ***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.

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. Figure 14.
