Negative voltage regulator using an ECG923 or ECG923D precision regulator IC


ECG923 ECG218
Negative voltage regulator (15 volts) using an ECG923 or ECG923D precision regulator IC. For metal can applications, where Vz is required, an external 6.2-volt zener should be connected in series with the regulated output. R1 is 3.65 ohms and R2 is 11.5 ohms for a ±5% fixed output (courtesy GTE Sylvania Incorporated).
