GL39500 Datasheet | Gleam

Description The GL39500 series is 5.0A low-dropout linear voltage regulators that provide a low-voltage, high-current output with a minimum of external ponents. The GL39500 series offers extremely low dropout (typically 400m V at 5.0A) and low ground current (typically 70m A at 5.0A). The GL39500 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 500m V over all operating conditions allows the GL39500 series to provide 2.5V from a supply as low as 3V or 1.8V.The GL39500 series also has fast transient response, for heavy switching applications. The device requires only 47μ F of output capacitance to maintain stability and achieve fast transient response. The GL39500 series is fully protected with overcurrent limiting, thermal shutdown, reversed-battery protection, reversed-lead insertion protection, and reversed-leakage protection. The GL39501 series offers a TTL-logic-patible enable pin and an error flag that indicates undervoltage and overcurrent conditions. Offered in a fixed voltages, 1.8V and 2.5V, the GL39500 series es in the TO-220 and TO-263 packages and is an ideal upgrade to older, NPNbased linear voltage regulators.
