Description
The ROB317 is an adjustable three-terminal voltage stabilizer, an analog integrated circuit listed in the Agenda radioelectronistului (2nd edition, 1989) among the integrated circuits made in Romania by ICCE (CCSIT-CE), in TO-39 and TO-3 packages [1]. Its pinout is in the Gallery.
Coded as (Romanian system, internal CCSIT-CE code) [2]:
| Part | Meaning |
|---|---|
| RO | manufacturer’s code: RO (Romania) |
| B | bipolar integrated circuit |
| 317 | identification number |
The Agenda radioelectronistului (2nd edition, 1989) gives the parameters of the ROB317 in the table of DC voltage stabilizers made in Romania by IPRS Băneasa and CCSIT-CE (section 35.3) [3]: absolute maximum ratings and electrical characteristics over the full temperature range; they are in the specifications.
Notes on the table of section 35.3 [3]: KU, KL and KT are given with the units printed in the table (the column headings give % VO).
