L200 Datasheet | STMicroelectronics

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 ABSOLUTE MAXIMUM RATINGS Symbol Vi Vi ∆Vi-o Io Ptot Tstg Top DC Input Voltage Peak Input Voltage (10 ms) Dropout Voltage Output Current Power Dissipation Storage Temperature Operating Junction Temperature for L200C for L200 Parameter 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.
