GL39100 Datasheet | Gleam

Description The GL39100 series is 1.0A low-dropout linear voltage regulators that provide a low-voltage, high-current output from an extremely small package. The GL39100 series offers extremely low dropout (typically 410m V at 1.0A) and low ground current (typically 12m A at 1.0A). The GL39100 is a fixed output regulator offered in the SOT-223 and TO-252 package. The GL39101 and GL39102 are fixed and adjustable regulators, respectively, in a thermally enhanced power 8lead SOP (small outline package). The GL39100 series is ideal for PC add-in cards that need to convert from standard 5V to 3.3V, 3.3V to 2.5V or 2.5V to 1.8V. A guaranteed maximum dropout voltage of 630m V over all operating conditions allows the GL39100 series to provide 2.5V from a supply as low as 3.13V and 1.8V from a supply as low as 2.43V. The GL39100 series is fully protected with overcurrent limiting, thermal shutdown, and reversed-battery protection. Fixed voltages of 5.0V, 3.3V, 2.5V, 1.8 and 1.5V are available on GL39100/1 with adjustable output voltages to 1.24V on GL39102.
