High-Temperature, 10V, 1A,
Preliminary datasheet
Version 0.0 (09/2004)
Low-Dropout SOI-CMOS Voltage Regulator.
Features
General Description
•
•
•
•
11V to 25V input Voltage @100mA
The CHT-LD-100 is a 1A, low-dropout
linear voltage regulator compatible with
high-temperature environments. Typical
operation temperature range extends from
-30°C to 225°C.
12V to 25V input Voltage @1A
Max 1A output current @ 225°C
60dB input ripple rejection
(0-100Hz)
The circuit is stable throughout the whole
temperature range and with a large choice
of capacitive loads.
•
•
Cload from 100nF to 1000µF, large
ESR range
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 is 2V with a
1A load and 1V for load currents lower
than 100mA. The input voltage may span
from 11 Volts to 25 Volts.
•
•
The circuit is a one-die solution.
CHT-LD-100 is available in die and
packages (currently TO-3 and TO-220) on
demand.
•
•
The start-up is operative over the
whole temperature range
Latch-up free
Applications
Power supplies for high-temperature
electronic systems used in Well logging,
Automotive, Aeronautics or Aerospace
applications.

Notes:
(1) Above 225°C, a minimum load current of few mA (<10 mA) could be required.
(2) Power dissipation depends on packaging. For a package with 5°C/W (Rth),
Pmax=(Max junction temperature – Environment temperature)/Rth.
