The S9V11F3S5CMA switching step-up/step-down regulator efficiently produces a fixed 3.3V (default) or 5V (selectable) output whether it is higher or lower than the input voltage, which can range from 2V to 16V. (Note: minimum start-up voltage is 3V, but it operates to 2V after that.) The regulator also has a precision-adjustable low-voltage cutoff with hysteresis that can be used to prevent battery over-discharge. The compact module can supply a typical output current of up to 1.5A when the input voltage is close to the output voltage.

  • Minimum Operating Voltage: 2V
  • Maximum Operating Voltage: 16V
  • Maximum Output current: 1.5A
  • Output Voltage: 3.3V
  • Reverse Voltage Protection: No
  • Maximum Quiescent Current: 1mA
  • Low-Voltage Cutoff: Adjustable

Please Note:

  • The minimum startup voltage is 3V, but the regulator can operate down to 2V after startup.
  • Under typical conditions, where the input voltage is close to the output voltage. Maximum output current can be higher when stepping down and lower when stepping up.
  • Output can be changed to 5V by driving the SEL pin over 1.1V.
  • With no load. Actual quiescent current depends on input voltage; it is typically under 300µA when the input voltage is close to the output voltage.
