L200 ® ADJUSTABLE VOLTAGE AND CURRENT REGULATOR
ADJUSTABLE OUTPUT CURRENT UP TO 2 A
(GUARANTEED UP TO Tj = 150 °C)
ADJUSTABLE OUTPUT VOLTAGE DOWN TO
2.85 V
INPUT OVERVOLTAGE PROTECTION (UP TO
60 V, 10 ms)
SHORT CIRCUIT PROTECTION
OUTPUT TRANSISTOR S.O.A. PROTECTION
THERMAL OVERLOAD PROTECTION
LOW BIAS CURRENT ON REGULATION PIN
LOW STANDBY CURRENT DRAIN DESCRIPTION
The L200 is a monolithic integrated circuit for voltage and current programmable regulation. It is
available in Pentawatt® package or 4-lead TO-3
metal case. Current limiting, power limiting, thermal
shutdown and input overvoltage protection (up to Pentawatt® TO-3 (4 lead) 60 V) make the L200 virtually blow-out proof.
The L200 can be used to replace fixed voltage
regulators when high output voltage precision is
required and eliminates the need to stock a range
of fixed voltage regulators. ABSOLUTE MAXIMUM RATINGS
