STRUCTURE
Silicon Monolithic Integrated Circuit
TYPE
Positive and Negative Variable Linear Regulator
PRODUCT SERIES
ＢＤ３９８８ＦＶ
FEATURES
1. Built-in positive (REG1) and negative (REG2) Linear Regulator for CCDs/ Variable output/
Low saturation voltage type.
2. Built-in Discharge circuit. Negative output voltage (REG2) turns off immediately,
after STB turns off.
