FEATURES APPLICATIONS
The HTVREF05 is a precision high-reliability monolithic
voltage reference fabricated with Honeywell’s
dielectrically isolated high-temperature (HTMOS®) pro-
cess. It is designed specifically for applications with ex-
tremely wide temperature ranges of -55 to +225°C, such
as down-hole oil well, aerospace, turbine engine and
industrial control. Typically, parts will operate up to
+250°C, with derated performance. All parts are burned in
to eliminate infant mortality.
The HTVREF05 provides a high temperature stable 5.0V
output, or bandgap reference for external biasing
schemes. Output current is 8mA; power supply current is
only 1.5mA.

HTVREF05
Figure 1. HTVREF05DC optimum load regulation pinout. The VOUT
can either source or sink current (sourcing current shown).
Figure 3. HTVREF05DC is the recommended circuit for CLOAD ≥100pF
pinout, where Cload is due to extra cable capacitance.
OPTIONAL CONFIGURATIONS
Figure 4. HTVREF05DC recommended trimming configuration. Vout
may be trimmed by adding external resistor R1 to lower Vout, or
adding R2 to raise Vout.
