The 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 dissipation
of the external pass transistor during fault conditions. When the load current
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-ratio
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 control,
high initial load demands and short circuit protection may both be accommodated
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 inclusion
of under-voltage lockout (UVLO) and thermal shutdown.

We Purchase Surplus Stock!!! 

If you or your company has items similar to the above, or indeed any electronic components surplus to requirements, please contact us with details as we are keen to increase our stock profile.

 As many of our lines come in to us as surplus – sometimes from high end ‘Milspec’ type manufacturers we try to pass on our savings to our customers – often selling industrial grade or military spec components rather than the commercial equivalent.
