G955
2.85V 1A Low Dropout Regulator
General Description
The G955 positive 2.85V voltage regulator
features the ability to source 1A of output
current with a dropout voltage of typically
0.5V over the entire operating temperature
range. A low quiescent current is provided
over the entire current output current range.
The typical quiescent current is 0.4mA.
Furthermore, the quiescent current is smaller
when the regulator is in the dropout mode
( VIN < 2.85V).
Familiar regulator features such as over
temperature, over current, and over voltage
protection circuits are provided to prevent it
from being damaged by abnormal operating
conditions.
