Description

The ROB305 is a positive 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 a TO-99 package [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
305 identification number

The Agenda radioelectronistului (2nd edition, 1989) gives the parameters of the ROB305 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). The column of the minimum output current gives, where marked with a footnote, the quiescent current IB.
