RT9069-50GSP

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

The RT9069-50GSP is a low-dropout (LDO) linear voltage regulator manufactured by Richtek Technology Corporation. It features a high input voltage range of 3.5V to 36V and provides a fixed 5V output with a maximum current capacity of 200mA. The device offers ultra-low quiescent current of 2µA, ensuring minimal power consumption in standby modes. Key electrical characteristics include a typical dropout voltage of 180mV at full load and a power supply rejection ratio (PSRR) of 70dB at 1kHz. It operates within a temperature range of -40°C to +85°C and includes an enable function for power management.

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

Verify the specific suffix 'GSP' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the fixed 5V output variant matches the design requirement, as other voltage options exist within the RT9069 family. Cross-reference RoHS compliance status with the latest product declaration documents provided by Richtek Technology Corporation prior to procurement.

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

Select this component when designing systems that require regulation from high-voltage sources such as 24V industrial buses down to 3.3V or 5V logic levels. The low quiescent current makes it ideal for applications where energy conservation is critical. Consider thermal dissipation requirements based on the voltage differential between input and output at the expected load current of 200mA.

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

The RT9069 series belongs to Richtek's portfolio of general-purpose LDO regulators designed for consumer electronics and industrial applications.
