Component qualification in accordance with JEDEC and industry
standards to ensure reliable operation over an extended
temperature range. This includes, but is not limited to, Highly
Accelerated Stress Test (HAST) or biased 85/85, temperature
cycle, autoclave or unbiased HAST, electromigration, bond
intermetallic life, and mold compound life. Such qualification
testing should not be viewed as justifying use of this component
beyond specified performance and environmental limits.

The UC2832 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 UC2832 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.
