Voltage Stabilizers
DO-204AH (DO-35 Glass)
Features
• Temperature-Compensated Stabilizing Circuits
• Monolithic linear integrated circuits with
extremely short thermal run-in time producing a
constant temperature-compensated voltage. They
are particularly suitable for stabilizing the tuning
voltage in radio and TV tuners employing voltage-
variable capacitance diodes.

Notes: (1) Valid provided that leads are kept at ambient temperature at a distance of 8 mm from case
(2) At the end of this time ∆VZ has reached 90% of its final value ∆VZ max. ∆VZ max = VZ (a) – VZ (0), where VZ (0) = VZ in the instant of turn-on
and VZ (a) = VZ at thermal equilibrium
(3) Tested with pulses tp = 5ms
