In order to obtain lower dropout voltage and faster transient response, which is critical for low voltage applications , the HPL1117 has been optimized. The device is available in an adjustable version and fixed output voltages of 1.8V, 2.5V, 2.85V, 3.3V and 5V. The output available voltage range of an adjustable version is from 1.25~10.7V with an input supply below 12V. Dropout voltage is guaranteed at a maximum of 1.3V at 1A. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures.

By placing a resistor between these two terminals, a constant Current is caused to flow through R1 and down through R2 to set the overall output voltage. Normally this current is chosen to be the specified minimum load current of 10mA. For fixed voltage devices R1 and R2 are included in the device.

Load regulation will be limited by the resistance of the wire connecting the regulator to the load. The data sheet specification for load regulation is measured at the output pin of the device. Best load regulation is obtained when the top of the resistor divider (R1) is tied directly to the output pin of the device, not to the load. For fixed voltage devices the top of R1 is internally connected to the output, and the ground pin can be connected to low side of the load. If R1 were connected to the load, RP is multiplied by the divider ratio, the effective resistance between the regulator and the load would be: Rp X (1+ R2 ), Rp = Parasitic Line Resistance R1 10 Output Capacitor The HPL1117 requires an output capacitor to maintain stability and improve transient response. Proper capacitor selection is important to ensure proper operation. The HPL1117 output capacitor selection is dependent upon the ESR (equivalent series resistance) of the output capacitor to maintain stability. When the output capacitor is 10uF or greater, the output capacitor should have an ESR less than 1Ω.This will improve transient response as well as promote stability. A lowESR solid tantalum capacitor works extremely well and provides good transient response and stability over temperature.  Copyright HIPAC Semiconductor, Inc. Rev.
