GM6610x Series
1.0A ULTRA LOW DROPOUT VOLTAGE
REGULATORS
Description
The GM66100/1/2 series are 1A ultra low-dropout
linear voltage regulators that provide low-voltage,
high output current from an extremely small
package.
The GM66100/1/2 offers extremely low dropout
(typically 410 m V at 1A) and low ground current
(typically 12mA at 1A).
The GM66100 offers 3 Lead packages with a fixed
output voltage options while GM66101/2 offer SO8
packages for fixed and adjustable output voltages
accordingly.
The GM66100/1/2 is ideal for PC add-in cards that
need to convert from standard 5V to 3.3V, 3.3V to
2.5V or 2.5V to 1.8V. A guaranteed maximum
dropout voltage of 630mV over all operating
conditions allows the GM66100/1/2 provide 2.5V
from a supply as low as 3.13V and 1.8V from a
supply as low as 2.43V.
The GM66100/1/2 is fully protected with over
current limiting, thermal shutdown, and reversed-
battery protection.
