The UC2832 and UC3833 series of precision linear regulators include all the
control functions required in the design of very low dropout linear regulators.
Additionally, they feature an innovative duty-ratio current limiting technique
which provides peak load capability while limiting the average power dissipa-
tion of the external pass transistor during fault conditions. When the load cur-
rent reaches an accurately programmed threshold, a gated-astable timer is
enabled, which switches the regulator’s pass device off and on at an externally
programmable duty-ratio. During the on-time of the pass element, the output
current is limited to a value slightly higher than the trip threshold of the duty-ra-
tio timer. The constant-current-limit is programmable on the UCx832 to allow
higher peak current during the on-time of the pass device. With duty-ratio con-
trol, high initial load demands and short circuit protection may both be accom-
modated without extra heat sinking or foldback current limiting. Additionally, if
the timer pin is grounded, the duty-ratio timer is disabled, and the IC operates
in constant-voltage/constant-current regulating mode.
These IC’s include a 2 Volt (±1%) reference, error amplifier, UVLO, and a high
current driver that has both source and sink outputs, allowing the use of either
NPN or PNP external pass transistors. Safe operation is assured by the inclu-
sion of under-voltage lockout (UVLO) and thermal shutdown.
The UC3833 family includes the basic functions of this design in a low-cost, 8-
pin mini-dip package, while the UC2832 series provides added versatility with
the availability of 14 pins. Packaging options include plastic (N suffix), or ce-
ramic (J suffix). Specified operating temperature ranges are: commercial (0°C
to 70°C), order UC3832/3 (N or J); and industrial (–40°C to 85°C), orderUC2832/3 (N or J). Surface mount packaging is also available.
