L194-12
LINEAR INTEGRATED CIRCUITS
POSITIVE VOLTAGE REGULATORS WITH RECTIFYING BRIDGE
• OUTPUT VOLTAGE: 5V, 12V AND 15V
• OUTPUT CURRENT UP TO 500 mA
• SHORT CIRCUIT PROTECTION
• THERMAL OVERLOAD PROTECTION
• OVERVOLTAGE PROTECTION (60V - 10 ms)
The L 194-5, L 194-12 and L 194-15 are fixed voltage regulators assembled in Pentawatt ® package.
They incorporate a rectifying diode bridge with 7A surge current capability.
