GM66500 SERIES
5A ULTRA LOW - DROPOUT REGULATOR
Description
Features
The GM66500 series is 5.0A low-dropout linear voltage reg-
ulators that provide a low-voltage, high-current output with
a minimum of external components.
The GM66500 series offers extremely low dropout
(typically 400mV at 5.0A) and low ground current (typically
70mA at 5.0A).
The GM66500 series is ideal for PC add-in cards that need
to convert from standard 3.0V to 2.5V and 2.5V to 1.8V,
down to new, lower core voltages. A guaranteed maximum
dropout voltage of 500mV over all operating conditions
allows the GM66500 series to provide 2.5V from a supply
as low as 3V. The GM66500 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 GM66500 series is fully protected with overcurrent
limiting, thermal shutdown, reversed-battery protection,
reversed-lead insertion protection, and reversed-leakage
protection.
The GM66501 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 GM66500 series comes in the TO-220 and
TO-263 packages and is an ideal upgrade to older, NPN-
based linear voltage regulators.
