UC3832 General Description
The UC1832 and UC1833 series of precision linear regulators include all the ontrol functions required in the design of very low dropout linear regulators.Additionally, they feature an innovative duty-ratio current limiting technique hich provides peak load capability while limiting the average power dissipation f the external pass transistor during fault conditions. When the load current eaches an accurately programmed threshold, a gated-astable timer is nabled, which switches the regulator’s pass device off and on at an externally rogrammable duty-ratio. During the on-time of the pass element, the output urrent is limited to a value slightly higher than the trip threshold of the duty-ratio imer. The constant-current-limit is programmable on the UCx832 to allow igher 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 ithout extra heat sinking or foldback current limiting. Additionally, if he timer pin is grounded, the duty-ratio timer is disabled, and the IC operates n constant-voltage/constant-current regulating mode.
These IC’s include a 2 Volt (±1%) reference, error amplifier, UVLO, and a high urrent driver that has both source and sink outputs, allowing the use of either PN or PNP external pass transistors. Safe operation is assured by the inclusion f under-voltage lockout (UVLO) and thermal shutdown.
The UC1833 family includes the basic functions of this design in a low-cost, 8-pin mini-dip package, while the UC1832 series provides added versatility with he availability of 14 pins. Packaging options include plastic (N suffix), or ceramic J suffix). Specified operating temperature ranges are: commercial (0°C o 70°C), order UC3832/3 (N or J); industrial (–25°C to 85°C), order UC2832/3 N or J); and military (–55°C to 125°C), order UC1832/3J. Surface mount ackaging is also available.
