Note 1:
All devices are 100% production tested at TA = +25°C and are guaranteed by design for TA = TMIN to TMAX, as specified.
Note 2:
Temperature coefficient is measured by the “box” method, i.e., the maximum ΔVOUT/VOUT is divided by the maximum ΔT.
Note 3:
Dropout voltage is defined as the minimum differential voltage (VIN - VOUT) at which VOUT decreases by 0.1% from its original value at VIN = 5.0V for VOUT = 2.5V and VOUT = 3.3V, and VIN = 5.5V for VOUT = 5.0V).
Note 4:
Thermal hysteresis is defined as the change in +25°C output voltage before and after cycling the device from TMAX to TMIN. www.analog.com Analog Devices │ 5
