GM66500 SERIES
5A ULTRA LOW - DROPOUT REGULATOR
Description
The GM66500 series is 5.0A low-dropout linear
voltage regulators 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 under
voltage 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, NPNbased linear
voltage regulators.
