C317
C317 is UPC317 manufactured by NEC.
DESCRIPTION
The µPC317 is an adjustable 3-terminal positive voltage regulator, which has 1.5 A capable for the output current.
..The output voltage can be set any value between 1.3 V and 30 V by two external resistors.
FEATURES
- - Output current excess of 1.5 A On-chip some protection circuit (over current protection, SOA protection and thermal shut down).
