LN1139BAMR-G

PMIC - Voltage Regulators - Linear

LDOVoltage RegulatorCMOSProgrammable

The LN1139BAMR-G is a 300mA programmable LDO voltage regulator in a SOT-23-5L package, featuring low power consumption and built-in protection circuits.

Best for

  • Battery-powered portable devices
  • Mobile and cordless phones
  • Portable AV equipment

Avoid if

  • Applications requiring fixed output voltages without external feedback components.

Check before use

  • Ensure the feedback resistor network (R1, R2) is correctly calculated for the desired output voltage (Vout = (1+R1/R2) * 0.8V).
