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 eight fixed output voltages of 1.5 V,
1.8 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.
