RT9022GU6

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

The RT9022GU6 is a positive adjustable linear regulator manufactured by Richtek USA Inc., classified under PMIC LDO regulators. It provides a single output with a maximum current of 60mA and operates within an input voltage range up to 20V. The output voltage is adjustable from 1.25V to 19.7V. Key electrical parameters include a quiescent current of 80 µA, a dropout voltage of 0.3V at 30mA, and power supply rejection ratios of 65dB at 120Hz and 55dB at 10kHz. The device features enable and soft-start control, along with overcurrent and thermal shutdown protection. It is housed in a SC-70-6 package and supports surface mount installation.

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

Verify component status as the RT9022GU6 is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with RoHS3 standards if environmental compliance is required. Check for moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Validate that the SC-70-6 package fits the target PCB footprint constraints.

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

Select this component when a low-cost, adjustable LDO with moderate output current is needed. The 60mA limit suits light loads, while the 20V input range allows flexibility. Consider the 80 µA quiescent current for battery efficiency. Compare PSRR performance against noise-sensitive downstream circuits. Ensure the SC-70-6 package size meets spatial limitations. Evaluate thermal dissipation needs based on input-output voltage differential and load current.
