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 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.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously . If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
1. This device series contains ESD protection and exceeds the following tests:
Human Body Model 2000 V per MIL−STD−883, Method 3015.
Machine Model Method 200 V.
2. Internal thermal shutdown protection limits the die temperature to approximately 175°C. Proper heatsinking is required to prevent activation.
The maximum package power dissipation is:
3. The regulator output current must not exceed 1.0 A with Vin greater than 12 V.
