Product details

2A LDO for noise-sensitive rails

The RAA214023GNP#HC0 is a 2A low-dropout linear regulator from Renesas, part of the RAA2140xx family, designed to deliver a clean, adjustable supply rail from 0.8V up to 3.95V with a maximum input of 5.5V. Its PSRR of 84dB at 120Hz drops to 52dB at 1MHz, meaning it rejects line-frequency ripple well but lets high-frequency switching noise from a downstream converter pass through — pair it with a post-LDO filter if your load is sensitive above 1MHz.

Dropout and headroom

Quiescent current is 300µA typical, a reasonable overhead for a 2A LDO; the Enable and Power Good control features let the system shut down the regulator when the load is idle, cutting Iq entirely.

Protection and temperature grade

Built-in protection covers Over Current, Over Temperature, Short Circuit, and Under Voltage Lockout (UVLO) — the regulator survives output shorts and thermal runaway without external clamping.

Frequently asked questions

What is the PSRR of the RAA214023GNP#HC0?

PSRR is 84dB at 120Hz, decreasing to 52dB at 1MHz. The 84dB figure at line frequency means excellent rejection of mains ripple, but the roll-off above 100kHz means high-frequency switching noise from a buck converter upstream will couple through unless an additional LC filter is placed ahead of the LDO.
