TYPICAL CHARACTERISTICS

ZRT050

NOTES

(a)

Output change with temperature (VR)

The absolute maximum difference between

the maximum output voltage and the

minimum output voltage over the specified

temperature range

VR = Vmax - Vmin

(b)

Output temperature coefficient (TCVR)

The ratio of

the output change with

temperature to the specified temperature

range expressed in ppm/°C

TcVR =

∆VR x 106

VR x ∆T

ppm

⁄ °C

∆T= Full temperature range

(c)

Operating current (IR)

Maximum operating current must be

derated as indicated in maximum ratings.

(d)

Slope resistance (RS)

The slope resistance is defined as :

RS =

change

in VR

specifiedcurrentrange

∆I = 5 - 0.5 = 4.5mA (typically)

(e)

Line regulation

The ratio of change in output voltage to the

change in input voltage producing it.
