GL39100 SERIES
1A ULTRA LOW - DROPOUT REGULATOR
Description
The GL39100 series is 1.0A low-dropout linear voltage re-
gulators that provide a low-voltage, high-current output
from an extremely small package.
The GL39100 series offers extremely low dropout (typically
410mV at 1.0A) and low ground current (typically 12mA at
1.0A).
The GL39100 is a fixed output regulator offered in the
SOT-223 and TO-252 package.
The GL39101 and GL39102 are fixed and adjustable
regulators, respectively, in a thermally enhanced power 8-
lead SOP (small outline package).
The GL39100 series 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 GL39100 series to
provide 2.5V from a supply as low as 3.13V and 1.8V from
a supply as low as 2.43V.
The GL39100 series is fully protected with overcurrent
limiting, thermal shutdown, and reversed-battery
protection.
Fixed voltages of 5.0V, 3.3V, 2.5V, 1.8 and 1.5V are
available on GL39100/1 with adjustable output voltages to
1.24V on GL39102.
