Technical content

  • 3 regulator ICs combined in 1 package
  • Insulated single inline package
  • Can be used with dropper type and switching type
  • 3 independent circuits for input and output respectively. Internal dissipation can be reduced since different input voltages can be applied.
  • Dropper type regulator IC is low-dropout voltage type with input/output voltage difference of 1V. Output ON/OFF control, variable output voltage (rise only) func- tion
  • Switching type: built-in separate excitation (60kHz), high efficiency of 80% or over
  • Each regulator has overcurrent protection and thermal protection circuit. n Applications
  • For stabilization of the secondary stage of switching power supplies

n Selecting External components for dropper type regulator Input capacitor (Approx. 47µF) Output capacitor (Approx. 47 to 100µF) l Low ESR capacitors are recommended for input and output when using them in low temperature conditions (0°C or less) n Selecting External components for switching type regulator Input capacitor (Approx. 100µF) Output smoothing capacitor (Approx. 330µF) l Input capacitor and output capacitor must satisfy allowable ripple current. l Low ESR capacitors are recommended for reducing output ripple voltage. l Low ESR capacitors are recommended for input and output when using them in low temperature conditions (0°C or less) Choke coil (200µH when VO is 3.3V or 5V, 300µH when VO is not 3.3V or 5V) l When its winding resistance is high, its efficiency may decrease and the rated value may not be achieved. l Pay attention to heat from the choke coil due to magnetic saturation caused by overload, short circuit of load, etc. because the overcurrent protection starting current is approx. 1A. Flywheel diode (Sanken AK04 recommended) l Use a Schottky barrier diode for D1, D2 and D3 and make sure that the reverse voltage applied to SW output terminal does not exceed the value (–1V) given in the maximum ratings. l If you use a fast recovery diode or any other diode, application of a reverse voltage generated from the recovery or ON voltage of the diode may damage the IC. l SLA3001M/3002M/3004M
