2 / 8 page KA350 2 Absolute Maximum Ratings Electrical Characteristics (VI-VO=5V, IO=1.5A, TJ=0 °C to + 125°C; PD ≤ PDMAX, unless otherwise specified) Note: 1. Regulation is measured at constant junction temperature. Changes in output voltage due to heating effects must be taken into account separately. Pulse testing with low duty cycle is used.
