... A A MICROELECTRONICS Description GM1117 of positive adjustable and fixed regulators is de- signed to provide 1.0A output with low dropout voltage per- formance. On-chip trimming adjusts the reference voltage to 1%. For usage on working in post regulators or micro- processor power supplies, low voltage operation and fast transient response are required. ...

... A detailed proce- dure for selecting this capacitor follows. Adjustable Operation The GM1117 has an output voltage range external resistor divider sets the output volt- age as shown in Figure 1. The regulator maintains a fixed 1.25V (typical) reference between the output pin and the adjust pin ...

... Output Voltage Sensing The GM1117 are three terminal regulators. For which, they cannot provide true remote load sensing. Load regulation is limited by the resistance of the conductors connecting the regulator to the load. For best results the GM1117 should be connected are as shown in IN Figure ...
