UC3833N [Unitrode]

Precision 1% Reference, Over-Current Sense Threshold Accurate to 5%, Programmable Duty-Ratio Over-Current Protection, 4.5 V to 36 V Operation, 100mA Output Drive, Source, or Sink, Under-Voltage Lockout. Additional Features of the UC2832 series: Adjustable Current Limit, Separate +VIN terminal, Programmable Driver Current Limit, Access to VREF and E/A(+), Logic-Level Disable Input. These ICs include a 2V (-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.
