Function Description
The SL4275 is a monolithically integrated low-dropout fixed voltage regulator in a 5-pin TO package. Input voltages up to 55V are regulated to an output voltage VQ of 5.0V. The chip can drive 450mA load and has short circuit protection and over temperature protection. When the output voltage VQ is lower than the typical value of 4.65V, the RQ pin of the chip will generate a low-level reset signal, and the reset delay time can be set by the D pin delay capacitor.
External component information
The SL4275 requires an input capacitor CI to compensate for trace effects. In order to ensure the stability of the regulation circuit, the output capacitor CQis necessary. Output capacitors with CQ≥ 22uF and ESR ≤ 5Ω guarantee stability over the operating temperature range.
Circuit description
The control op amp compares the reference voltage with a voltage proportional to the output voltage and drives the gate ofthe series MOS transistor through a buffer. In addition, a current-limiting control unit for the load current prevents oversaturation of the power components. The chip also integrates many internal circuits foroverload,over-temperature, and other protections.
