LINEAR INTEGRATED CIRCUIT
HIGH PRECISION HIGH VOLTAGE
REGULATOR
INPUT VOLTAGE UP TO 80V OUTPUT VOLTAGE ADJUSTABLE FROM 2 TO 77V POSITIVE OR NEGATIVE SUPPLY OPERATION SERIES. SHUNT, SWITCHING OR FLOATING OPERATION OUTPUT CURRENT UP TO 150 mA WITHOUT EXTERNAL PASS
TRANSISTOR ADJUSTABLE CURRENT LIMITING THERMAL PROTECTION
The L 146 is a monolithic integrated programmable voltage
regulator in 14-lead dual in-line plastic package and 10-lead Metal Can (TO-l00 type). It is made with high voltage technology and provides internal current limiting and thermal shut down protection; when current exceeds 150 mA an external
NPN or
PNP pass element may be used. Provisions are made for adjustable current limiting and remote shut down. The L 146 is intended to widen the application range of L 123 up to 80V.
