Product details

2V fixed LDO with 70dB PSRR

The ROHM BU20TD3WG-TR is a 200mA positive fixed-output LDO regulator delivering 2V from a maximum 6V input rail. Its 70dB PSRR at 1kHz means upstream switching noise at that frequency is attenuated by a factor of ~3000 — useful for powering analog front-ends or sensor bias rails where ripple on the supply couples into the signal path.

Quiescent current and protection

Quiescent current is 60 µA typical — low enough for battery-powered equipment that spends most of its time in a light-load or sleep state. Built-in over-current and over-temperature protection guard against output shorts or excessive ambient heat; the part shuts down rather than exceeding its safe operating area. The Enable control pin lets the system pull the output to zero and drop Iq further when the regulated rail is not needed — a common requirement in power-sequenced designs.

Active production and compliance

ROHS3 compliant, with no restricted substances above the threshold — no additional exemption paperwork needed for EU-market shipments.

Frequently asked questions

What is the PSRR of BU20TD3WG-TR?

The BU20TD3WG-TR lists 70dB PSRR at 1kHz, meaning ripple on the input at that frequency is attenuated by roughly 3000× — useful for powering noise-sensitive analog circuits.
