These are stress ratings only. Functional operation of the device at these or any conditions beyond the "recommended operating conditions" is not implied. Exposure to absolute maximum rated conditions may affect device reliability. NOTES: 1. Voltage values are with respect to the anode except as noted. 2. Maximum power dissipation is a function of T , q and T . Maximum allowable power dissipation at any allowable ambient temperature is J(max) JA A P = (T D J(max) 3.

side as an error amplifier, and feedback to the primary side is provided via a photocoupler. Figure 16. Typical Shunt Regulator/ Error Amplifier

This refers to the determination of the gain frequency characteristic of the shunt regulator as an error amplifier. Taking the configuration in figure 16, the error amplifier characteristic is as shown in figure 17. Figure 17. GM1431 Error Amplification Characteristic , and is approximately 50 dB. the shunt regulator V = 3 V, the following values are found.
