NOTES:
1. Limits are production tested at Tamb = +25 °C. All devices are 100% production tested at 25 °C. Limits over the operating tempreature are
guaranteed by design.
2. Accuracy
±2 °C over temperature range guaranteed by design and characterization.
3. The dropout voltage is defined as VIN – VOUT, where VOUT is 100 mV below the value of VOUT for VIN = VOUT + 0.5 V.
4. Time needed for VOUT to reach 95% of VOUT(nom).
