AMS116 ADMOS [Advanced Monolithic Systems], AMS116 Datasheet - Page 6

• Manufacturer Part Number: AMS116
• Description: 100mA LOW DROPOUT VOLTAGE REGULATOR
• Manufacturer: ADMOS [Advanced Monolithic Systems]

TYPICAL APPLICATIONS
*Required if regulator is located far from power supply filter.
**C2 must be at least 100µF to maintain stability; it can be increased
without bound to maintain regulation during transients and it should be
located as close as possible to the regulator. This capacitor must be rated
over the same operating temperature range like the regulator. The ESR
of this capacitor is critical (see curve).
