Global Mixed-mode Technology Inc. G1085 3A Adjustable Low-Dropout Linear Regulator Features Available in Adjust Version Space Saving TO-252 Package and TO-263 Package Internal Short Circuit Current Limiting Internal Over Temperature Protection Output Current 3A General Description The G1085 is a low dropout linear regulator with a dropout of 1.2V at 3A 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 G1085 provides over temperature and over current protection circuits to prevent it from being damaged by abnormal operating conditions. The G1085 is available in TO-252 package and TO- 263 packages. A minimum of 100µF tantalum electrolytic capacitor is required at the output to improve the transient response and stability.
