RT9169H-26GB

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

The RT9169H-26GB is a CMOS low dropout (LDO) regulator manufactured by Richtek Technology Corporation. It provides a fixed output voltage of 2.6V with a maximum load current of 100mA. The device features an ultra-low quiescent current of 4μA and operates within a wide input voltage range of 2V to 6V. It achieves a low dropout voltage of 450mV at full load and includes current limiting protection. Stability is ensured using only a 1μF output capacitor, and the component offers high power supply rejection ratio performance.

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

Verify the specific suffix 'GB' against official Richtek documentation to confirm lead plating and package details. Ensure the ordering code matches the required 2.6V output designation. Confirm RoHS compliance status and Pb-free requirements align with project specifications before procurement.

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

Select this LDO for applications requiring stable regulation from single-cell batteries or low-voltage sources. The 4μA quiescent current makes it suitable for portable devices where standby power conservation is critical. Verify that the input voltage remains within the 2V to 6V range and that the load does not exceed 100mA.

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

The RT9169H series consists of 100mA CMOS LDO regulators designed for portable electronics. The 'H' variant specifically denotes the SOT-23-5 package type, which includes a Chip Enable pin. This distinguishes it from other package options like TO-92 or SOT-89 found in the broader RT9169 family.

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

Compatible substitutes include other parts from the RT9169 series with matching output voltages and package types. Verify electrical parameters such as quiescent current and dropout voltage when cross-referencing with alternative LDO regulators.
