STRUCTURE
Silicon Monolithic Integrated Circuit
TYPE
Positive and Negative Variable Linear
Regulator
PRODUCT SERIES
BD3989FV
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.
