Voltage Regulators - Linear

5 V LDO150 mA40 V inputlow quiescent currentSOT-23-3SOT-89-3

OC7550 is a fixed 5.0 V, 150 mA LDO from OCX with a family input rating up to 40 V and low quiescent current.

Best for

  • Low-current 5 V rails
  • Battery-powered electronics
  • Low-power microcontroller supplies

Avoid if

  • Input voltage is too close to 5.0 V for the required load current
  • Load current exceeds 150 mA
  • High efficiency is required at large input-to-output voltage differences

Check before use

  • Verify exact SOT-23-3 or SOT-89-3 package selection
  • Check dropout and input-voltage headroom
  • Calculate thermal dissipation
  • Fit at least 2.2 µF effective output capacitance
