ET515DCEYB

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

The ET515DCEYB is a dual low-noise linear voltage regulator (LDO) manufactured by ETEK Microelectronics. It provides two independent positive fixed output voltages ranging from 1.8V to 3.3V with a maximum output current of 150mA per channel. The device operates within a supply voltage range of 1.65V to 4.5V and features a power supply rejection ratio (PSRR) optimized for noise-sensitive applications. Designed for surface mount assembly, it is housed in a compact 6-DFN package measuring 1.2mm x 1.2mm. The component supports an operating temperature range from -40°C to 85°C.

• Audio equipment needing low-noise power supplies
• RF modules and communication interfaces
• Embedded systems with mixed-signal requirements

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

Verify the specific output voltage configuration during procurement, as the ET515DCEYB designation implies a fixed output range rather than adjustable. Confirm the suffix 'CYB' corresponds to the required tape-and-reel packaging and lead finish specifications. Ensure compatibility with the target PCB footprint for the 6-DFN (1.2x1.2mm) package. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance or environmental declarations before finalizing orders.

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

Select this component when dual isolated LDOs are required in a minimal footprint. The 150mA current capability suits moderate load applications, while the low-noise characteristic addresses interference concerns in audio or RF sections. Compare against single-channel alternatives if only one rail is needed to optimize board space. Consider the input-output voltage differential to ensure adequate dropout performance across the full operating temperature range.
