3 / 18 page 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). Table 1.
