The stability is ensured with a

decoupling capacitor between

VDD and VSS: COUT ≥ 10μF

with ESR ≤ 3Ω.

The current capability can be

increased up to 150mA by

using an external N channel

MOS transistor (see Figure 1).

The main characteristics for

choosing this component are

VT < 1.8V and BVDSS > 40V
