Application Information
GM6605 series linear regulators provide fixed and adju stable output voltages at currents up to 5.0A. These regulators are protected against over-current conditions and include thermal shutdown protection. The GM6605 has a composite PNP-NPN output transistor and require an output capacitor for stability. A detailed procedure for selecting this capacitor is as below: Stability Considerations The output compensation capac itor helps to determine three main characteristics of a linear regulator's performance: start-up delay, load transient response, and loop stability. The capacitor value and type is based on cost, availability, size, and temperature constraints. A tantalum or aluminum electrolytic capacitor is preferred, as a film or ceramic capacit or with almost zero ESR can cause instability. An aluminum electrolytic capacitor is the least expensive type. But when the circuit operates at low temperatures, both the value and ESR of the capacitor will vary widely. For optimum performance over the full operating temperature range, a tantalum capacitor is the best. A 22 µF tantalum capacitor will work fine in most applications. But with high current regulators, such as GM6605 higher capacitance values will improve the transient response and stability. Most applications for Gm6605 involve large changes in load current, so the output capacitor must supply instantaneous load current. The ESR of the output capacitor causes an immedi ate drop in output voltage given by: V = I x ESR In microprocessor applications an output capacitor network of several tantalum and ceramic capacitors in parallel is commonly used. This reduces overa ll ESR and minimizes the instantaneous output voltage drop under transient load conditions. The output capacitor network should be placed as close to the load as possible for the best results. Protection Diodes When large external capacitors are used with most linear regulators, it is wise to add protection diodes. If the input voltage of the regulator is shorted, the output capacitor will discharge into the output of the regulator. The discharge current depends on the value of capacitor, output voltage, and rate at which VIN drops. For GM6605, the discharge path is through a large junction, and protection diodes are normally not needed. However, if the regulator is used with large output capacitance values and the input voltage is instantaneously shorted to ground, damage can occur. In this case, a diode connected as shown above in Figure 1 is recommended. Figure 1. Protection Diode Scheme
