REF50Z/REF50D
5V MICROPOWER PRECISION REFERENCE
The REF50Z and REF50D are integrated circuits using
the bandgap principle to provide a precise stable reference
voltage of 5V. There are two package options available:
REF50Z in a plastic 3-pin TO-92 and REF50D in a miniature
surface mount package (MP8).
These references feature a recommended operating cur-
rent of 60µA to 5mA which make them ideal for all low power
and battery applications.

NOTES
1. Slope resistance (RREF
)
Slope resistance is defined as
RREF = Change in VREF over a specified current range
The change in reference current
2. Reference voltage temperature coefficient (TC VREF)
This is the normalised reference voltage change over temperature, divided by the change in temperature.
It is expressed in ppm/°C
TC VREF
=
∆VREF X 106 ppm/°C
VREF X ∆T
∆T = temperature change in °C
∆VREF = change in reference voltage over temperature change ∆T
