BD3987FV

The BD3987FV is designed as one kind of positive and negative variable linear regulator that has two points of 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.

The absolute maximum ratings of the BD3987FV can be summarized as:(1)positive supply voltage: +18 V and the negative supply voltage: -18 V;(2)power dissipation: 380 mW;(3)operating temperature range: -40 to +85 ;(4)storage temperature range: -55 to +125 ;(5)maximum junction temperature: 125 . And the operating conditions of this device are:(1)positive supply voltage: +15.0 to +18.0 V;(2)negative supply voltage of BD3987FV: -14.0 to -7.5 V;(3)REG1 output voltage: +14.0 to +16.0 V;(4)REG2 output voltage: -8.5 to -6.5 V;(5)output current 1: 25 mA;(6)output current 2: 50 mA.
