Precision Low Dropout Linear Controllers

The UC1832 and UC1833 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 Regulators 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 ICs 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 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 the availability of 14 pins. Packaging options include plastic (N suffix), or ce- ramic (J suffix). Specified operating temperature ranges are: commercial (0C to 70C), order UC3832 3 (N or J); industrial (25C to 85C), order UC2832 3 (N or J); and military (55C to 125C), order UC1832 3J. Surface mount packaging is also available. By Texas Instruments
