µPC317
3-TERMINAL POSITIVE ADJUSTABLE REGULATOR
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 protec-
tion, SOA protection and thermal shut down).
PIN CONFIGURATION (Marking Side)
3-pin plastic SIP (MP-45G)
