CHT-LDOS
Preliminary datasheet
Version 1.0 (05/2006)
High-Temperature,
2.5V; 3.3V; 5V; 5.5V; 9V; 10V; 12V; 13V or 15V,
1A, Low-Dropout SOI-CMOS Voltage Regulator
for symmetrical voltage applications.
General Description
The CHT-LDOS is a 1A, low-dropout linear
voltage regulator compatible with high-
temperature 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.
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.
CHT-LDOS is available in die and
packages (currently TO-3 and TO-254) on
demand.

Should be very similar to CHT-LDO datasheet
Figure 9: Typical max load current over T° vs. dropout
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.
Available packaging and pinout.
