sFeatures
•
•
•
•
Compact full-mold package (equivalent to TO220)
Output current: 1.5A
Low dropout voltage: VDIF≤1V (at IO=1.5A)
Variable output voltage (rise only)
May be used for remote sensing
• Output ON/OFF control terminal is compatible with LS-TTL. (It may be
directly driven by LS-TTL or standard CMOS logic.)
