NCP3335
High Accuracy Ultra−low Iq,
500 mA Low Dropout
Regulator
The NCP3335 is a high performance low dropout regulator that
entails all the required features for consumer electronics and
encompasses a unique design technology that allows for a high
accuracy of 0.9% over line and load regulation. This device
operates using a minimum output capacitance and is guaranteed to
be stable using any type of capacitor.
http://onsemi.com
With output voltage options at 2.5 V, 2.85 V, and 3.3 V, delivering
500 mA of current, this device is offered in a Micro8 package. It
contains thermal protection, current limitation and is lead free.

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.
NOTE: This device series contains ESD protection and exceeds the following tests:
