... G14 See the Applications Information section for more informa- tion on output capacitance. ADJ (Pin 5) LTC3025-1: Adjust Input. This is the input to the error amplifi er. The ADJ pin reference voltage is 0.4V referenced to ground. The output voltage range is 0.4V to 3.6V and is typically set by connecting ADJ to a resistor divider from OUT to GND ...

... A single ceramic capacitor as small as 1μF is all that is required for output bypassing. A low reference voltage allows the LTC3025-1 output to be programmed to much lower voltages than available in common LDOs (range of 0. 6V). The LTC3025-2/LTC3025-3/LTC3025-4 have fi ...

... C is discharged. OUT The LTC3025-1 operates at a relatively high gain of –0.7μV/mA referred to the ADJ input. Thus a load cur- rent change of 1mA to 500mA produces a –0.35mV drop at the ADJ input. To calculate the change referred to the output simply multiply by the gain of the feedback network (i ...
