RP109Q112D5-TR-FE

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The RP109Q112D5-TR-FE is a CMOS Low Dropout (LDO) voltage regulator manufactured by Nisshinbo Micro Devices. It provides a fixed output voltage of 1.15 V with a maximum output current of 150 mA. The device operates within an input voltage range of 1.4 V to 5.25 V and features a typical dropout voltage of 560 mV at full load. It includes internal protection against short circuits and thermal overload. The regulator is housed in a compact SC-88A-5 package, suitable for surface-mount applications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the exact output voltage (1.15 V) and package type (SC-88A-5) against your schematic requirements. Confirm that the 150 mA current rating meets your peak load demands. Ensure the operating temperature range (-40°C to +85°C) aligns with your environmental specifications. Check RoHS compliance status if required by your manufacturing standards.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a precise 1.15 V rail is needed from a single-cell lithium battery or similar supply. Its low dropout allows operation even as battery voltage drops near the output level. The small SC-88A-5 package aids in space-constrained designs. Consider the 150 mA limit for load planning; higher currents require alternative regulators.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the RP109Q series of low-voltage LDO regulators from Nisshinbo Micro Devices. The series is designed for energy-efficient power management in portable devices. The 'Q' suffix typically denotes specific quality or automotive-grade variants, though verification is recommended. The 'D5' indicates the 1.15 V output voltage code.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes include other RP109Q series parts with different fixed voltages (e.g., RP109Q113D5-TR-FE for 1.2 V). Cross-brand replacements must match the 1.15 V output, 150 mA current, and SC-88A-5 footprint. Verify pinout compatibility before substitution.
