Global Mixed-mode Technology Inc. G1084 5A Adjustable Low-Dropout Linear Regulator Features Available in Adjust Version TO-220, TO-252,TO-263 and TO-263T Package Internal Short Circuit Current Limiting Internal Over Temperature Protection Output Current 5A General Description The G1084 is a low dropout linear regulator with a dropout of 1.2V at 5A of load current. It is available in an adjustable version, which can set the output from 1.25V to 5V with only two external resistors. The G1084 provides over temperature and over current protection circuits to prevent it from being damaged by abnormal operating conditions. The G1084 is available in TO-220, TO-252, TO-263 and TO-263T packages. A minimum of 220µF tantalum electrolytic capacitor is required at the output to improve the transient response and stability.
