The LX8820 is an ultra low-
dropout single output positive-
voltage
linear
regulator has a precise, fixed
output capable of delivering 1.2
amps.
The LX8820 output is internally
programmed for 3.3V.
Regulator stability is maintained
with any capacitor ESR, allowing
ceramic, tantalum or electrolytic
types.
