Data Sheet

ADP2230

SPECIFICATIONS

VIN = VENx = 5.0 V, VOUT = 3.3 V, TJ = −40°C to +125°C for minimum/maximum specifications, and TA = 25°C for typical specifications,

unless otherwise noted. All limits at temperature extremes are guaranteed via correlation using standard statistical quality control (SQC).
