CS8371
8.0 V/1.0 A, 5.0 V/250 mA
Dual Regulator
with Independent Output
Enables and NOCAPt
The CS8371 is an 8.0 V/5.0 V dual output linear regulator. The
8.0 V ±5.0% output sources 1.0 A, while the 5.0 V ±5.0% output
sources 250 mA. Each output is controlled by its own ENABLE lead.
Setting the ENABLE input high turns on the associated regulator
output. Holding both ENABLE inputs low puts the IC into sleep mode
where current consumption is less than 10 mA.
The regulator is protected against overvoltage, short−circuit and
thermal runaway conditions. The device can withstand 45 V load dump
transients making suitable for use in automotive environments. ON’s
proprietary NOCAP solution is the first technology which allows the
output to be stable without the use of an external capacitor.
The CS8371 is available in a 7 lead TO−220 package with copper
tab. The tab can be connected to a heatsink if necessary.
