GL39300 SERIES
3A ULTRA LOW - DROPOUT REGULATOR
Description
The GL39300 series is 3.0A low-dropout linear voltage re-
gulators that provide a low-voltage, and high-current output
with a minimum of external components.
The GL39300 series offers extremely low dropout (typically
400mV at 3.0A) and low ground current (typically 36mA at
3.0A).
The GL39300 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 voltage. A guaranteed maximum
dropout voltage of 500mV over all operating conditions
allows the GL39300 series to provide 2.5V from a supply
as low as 3V or 1.8V. The GL39300 series also has fast
transient response. for heavy switching applications to
maintain stability and achieve fast response.
The GL39300 series is fully protected with overcurrent
limiting, thermal shutdown, reversed-battery protection,
reversed-lead insertion protection, and reversed-leakage
protection.
The GL39300 series offers a TTL-logic-compatible enable
pin, and an error flag that indicates under voltage and over
current conditions. Offered in a fixed voltages, 1.8V and
2.5V, the GL39300 series comes in the TO-263 and TO-
252 packages. and is an ideal upgrade to older, NPN-
based linear voltage regulators.
The GL39302 is adjustable version. And the GL39300/01 is
fixed version.
