NCP1117, NCV1117

1.0 A Low-Dropout Positive

Fixed and Adjustable

Voltage Regulators

The NCP1117 series are low dropout positive voltage regulators that

are capable of providing an output current that is in excess of 1.0 A

with a maximum dropout voltage of 1.2 V at 800 mA over

temperature. This series contains nine fixed output voltages of 1.5 V,

1.8 V, 1.9 V, 2.0 V, 2.5 V, 2.85 V, 3.3 V, 5.0 V, and 12 V that have no

minimum load requirement to maintain regulation. Also included is an

adjustable output version that can be programmed from 1.25 V to

18.8 V with two external resistors. On chip trimming adjusts the

reference/output voltage to within ±1.0% accuracy. Internal protection

features consist of output current limiting, safe operating area

compensation, and thermal shutdown. The NCP1117 series can

operate with up to 20 V input. Devices are available in SOT−223 and

DPAK packages.

NCP1117, NCV1117 APPLICATIONS INFORMATION Introduction Frequency compensation for the regulator is provided by capacitor Cout and its use is mandatory to ensure output stability. A minimum capacitance value of 4.7 mF with an equivalent series resistance (ESR) that is within the limits of 33 mW (typ) to 2.2 W is required. See Figures 12 and 13.
PAGE 10
NCP1117, NCV1117 Protection Diodes The second condition is that the ground end of R2 should be connected directly to the load. This allows true Kelvin sensing where the regulator compensates for the voltage drop caused by wiring resistance RW −. The NCP1117 family has two internal low impedance diode paths that normally do not require protection when used in the typical regulator applications. The first path connects between Vout and Vin, and it can withstand a peak surge current of about 15 A.
