1. The stability is ensured with a decoupling capacitor between VDD and VSS : C_OUT ≥ 10µF with ESR ≤ 3Ω.
2. The current capability can be increased up to 150mA by using an external N channel MOS transistor (see figure 1 page 2). The main
characteristics for choosing this component are : VT < 1.8V and BVDSS > 40V.
