... A Adjustable and 3.3 V Fixed Output Linear Regulator The NCP1086 linear regulator provides 1 3 adjustable output voltage. The adjustable output voltage device uses two external resistors to set the output voltage within a 1. 5.5 V range. The regulators is intended for use as post regulator and microprocessor supply ...

... The minimum load current is the minimum current required to maintain regulation. Normally the current in the resistor divider used to set the output voltage is selected to meet the minimum requirement. 7. Guaranteed by design, not 100% tested in production. 8. Thermal shutdown is 100% functionally tested in production. NCP1086 Parameter Wave Solder (through hole styles only) Note 1 Reflow (SMD styles only) Note 2 ...

... V output voltages at currents up to 1.5 A. The regulator is protected against overcurrent conditions and includes thermal shutdown. The NCP1086 series has a composite PNP−NPN output transistor and requires an output capacitor for stability. A detailed procedure for selecting this capacitor is included in the Stability Considerations section. ...

... tantalum capacitor will work for most reaches the point at applications, but with high current regulators such as the NCP1086 series the transient response and stability improve with higher values of capacitance. The majority of applications for this regulator involve large changes in load current, so the output capacitor must supply the instantaneous load current ...
