Description

Features

The GM66300 series is 3.0A low-dropout linear voltage reg-

ulators that provide a low-voltage, and high-current output

with a minimum of external components.

3.0A minimum guaranteed output current

500mV dropout voltage

Ideal for 3.0V to 2.5V conversion

Ideal for 2.5V to 1.8V conversion

1% initial accuracy

The GM66300 series offers extremely low dropout

(typically 400mV at 3.0A) and low ground current (typically

36mA at 3.0A).

Low ground current

The GM66300 series is ideal for PC add-in cards that need

to convert from standard 3.0V to 2.5V and 2.5V to 1.8,

down to new, lower core voltages. A guaranteed maximum

dropout voltage of 500mV over all operating conditions

allows the GM66300 series to provide 2.5V from a supply

as low as 3V or 1.8V . The GM66300 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.

Current limiting and Thermal shutdown

Reversed-battery protection

Reversed-leakage protection

Fast transient response

TO-220 and TO-263 packages

TTL/CMOS compatible enable pin (GM66301 only)

Error flag output (GM66301 only)

Adjustable version (GM66302 only)

The GM66300 series is fully protected with overcurrent

limiting, thermal shutdown, reversed-battery protection,

reversed-lead insertion protection, and reversed-leakage

protection.

Application

LDO linear regulator for PC add-in cards

High-efficiency linear power supplies

SMPS post regulator

The GM66301 series offers a TTL-logic-compatible enable

pin, and an error flag that indicates undervoltage and

overcurrent conditions. Offered in a fixed voltages, 1.8V

and 2.5V, the GM66300 series comes in the TO-220 and

TO-263 packages, and is an ideal upgrade to older, NPN-

based linear voltage regulators.

Multimedia and PC processor supplies

Low-voltage microcontrollers

Strong ARM processor supply

The GM66030 is adjustable version.
