8.0 V/1.0 A, 5.0 V/250 mA

Dual Regulator

with Independent Output

Enables and NOCAPt

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.

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.
