environments.
Typical
operation temperature range extends from
-30°C to 225°C.
The circuit is stable throughout the whole
temperature range and under a large
choice of capacitive loads.
•
Available on die or in custom package
on demand. (3-pins compatible)
Stand-by mode available. (4-pins)
Tungsten interconnects for long-term
reliability
The minimum dropout voltage (Vin-Vout) is
2V with a 1A load current at 225°C and 1V
for load currents lower than 400mA. The
dropout voltage can span from 1 Volts to
20 Volts(1).
•
•
The circuit is a one-die solution.
•
•
The start-up is operative over the
whole temperature range
CHT-LDOS is available in die and
packages (currently TO-3 and TO-254) on
demand.
Latch-up free

Notes:
(1) Vin max=30V
(2) Above 225°C (Tj), a minimum load current of few mA could be required.
(3) Max Power dissipation depends on packaging. CHT-LDOS in TO-3 or TO-254 packages presents a “junction-to-
case” thermal resistance of maximum 5°C/W (Rth).
(4) ppm are defined as [d(Vout)/d(T)]/Vout. For 5V mode, 40ppm corresponds to 200µV/°C.
(5) Defining “x” as the nominal voltage, the line regulation is better than x/5 mV/V.
(6) This includes the packaging parasitic resistor.
(7) Defining “x” as the nominal voltage, the typical quiescent current at 2V dropout can be approximated as
2.8+x/13 mA @ -30°C and 2.5+x/13 mA at 225°C.
(8) Defining “x” as the nominal voltage, the minimum power supply rejection ratio is …(tbd)….

Output Load, recommended specifications
CHT-LDOS
Resistances in series with capacitors represent the internal ESR of these capacitors.
For large capacitors:
CB= 0 to 1000µF
RB= 0.2 to ∞ Ω
For medium capacitors:
CM= 0 to 6µF
For small Capacitors:
CS= 100n to 220nF
RS=10m to 50m Ω
RM=0.1 to 1 Ω
Start-up conditions
The start-up is operative over the whole temperature range.
Refer to our application note for more details when using symmetrical voltages.

AC rejection, noise and maximum load current vs. dropout measurements have not been
performed yet on CHT-LDOS family. However, based on simulation results, measurements
result should be very similar to those presented in our CHT-LDO family datasheet.
