Overview
Precision Low Dropout Linear Controllers UC1832 UC2832/3 UC3832/3 FEATURES • 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 to Current Sense Ratio • Separate +VIN terminal • Programmable Driver Current Limit • Access to VREF and E/A(+) • Logic-Level Disable Input DESCRIPTION The UC2832 and 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 ...
