NOTE1: 100% production test at +25℃. Specifictations over the temperature range are guaranteed by design and characterization.
NOTE2: Output voltage accuracy : ±2%.
NOTE3: Line regulation is calculated by ΔVLINE = [(VOUT1 – VOUT2) / (ΔVIN x VOUT(NORMAL))] x 100. Where VOUT1 is the output voltage when VIN
= 5.5V, and VOUT2 is the output voltage when VIN = 3.6V, ΔVIN = 1.9V, VOUT (NORMAL) = 2.8V.
NOTE4: Load regulation is calculated by ΔVLOAD = [(VOUT1 – VOUT2) / (ΔIOUT x VOUT(NORMAL))] x 100. Where VOUT1 is the output voltage when
IOUT = 1mA, and VOUT2 is the output voltage when IOUT = 300mA. ΔIOUT = 0.299A, VOUT(NORMAL) = 2.8V.
NOTE5: The temperature coefficient is calculated by TCVOUT = [ΔVOUT / (ΔT x VOUT)]
