Typical Applications Circuit When using a negative regulator, bypass capacitors are a must on both the input and output. Recommended values are 2 µF on the input and 1 µF on the output. It is considered good practice to include a 0.1 µF capacitor on the output to improve the transient response (Fig. 1). These capacitors may mylar, ceramic, or tantalum, provided that they have IN 2 2µF 79XX 3 $Vout 0.1µF
