GL39300 Datasheet | Gleam

Description The GL39300 series is 3.0A low-dropout linear voltage regulators that provide a low-voltage, and high-current output with a minimum of external ponents. The GL39300 series offers extremely low dropout (typically 400m V at 3.0A) and low ground current (typically 36m A 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 500m V 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-patible 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 es in the TO-263 and TO252 packages. and is an ideal upgrade to older, NPNbased linear voltage regulators. The GL39302 is adjustable version. And the GL39300/01 is fixed version.
