Description
The GM66300 series is 3.0A low-dropout linear voltage reg-
ulators that provide a low-voltage, and high-current output
with a minimum of external components.
The GM66300 series offers extremely low dropout
(typically 400mV at 3.0A) and low ground current (typically
36mA at 3.0A).
The GM66300 series is ideal for PC add-in cards that need
to convert from standard 3.0V to 2.5V and 2.5V to 1.8,
down to new, lower core voltages. A guaranteed maximum
dropout voltage of 500mV over all operating conditions
allows the GM66300 series to provide 2.5V from a supply
as low as 3V or 1.8V . The GM66300 series also has fast
transient response, for heavy switching applications. The
device requires only 47µF of output capacitance to
maintain stability and achieve fast transient response.
The GM66300 series is fully protected with overcurrent
limiting, thermal shutdown, reversed-battery protection,
reversed-lead insertion protection, and reversed-leakage
protection.
The GM66301 series offers a TTL-logic-compatible enable
pin, and an error flag that indicates undervoltage and
overcurrent conditions. Offered in a fixed voltages, 1.8V
and 2.5V, the GM66300 series comes in the TO-220 and
TO-263 packages, and is an ideal upgrade to older, NPN-
based linear voltage regulators.
The GM66030 is adjustable version.
