BU27TD2WNVX-TL

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

The BU27TD2WNVX-TL is a single-output fixed positive low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed output voltage of 2.7 V with a maximum output current capability of 200 mA. The device operates within an input voltage range of 1.7 V to 6 V and features a typical power supply rejection ratio (PSRR) of 70 dB. Key electrical parameters include a typical dropout voltage of 280 mV, a maximum dropout voltage of 540 mV, a line regulation of 2 mV, and a load regulation of 10 mV. The quiescent operating current is specified at 35 uA, with a maximum power dissipation of 560 mW. The component supports surface-mount installation in an SSON004X1010-4 package and functions reliably across an operating temperature range from -40 C to +85 C.

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

Verify the specific suffix TL against official ROHM documentation to confirm tape-and-reel packaging configuration. Ensure the ordering part number matches the exact voltage variant required, as the series includes multiple fixed output options. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement specifications.

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

Select this component when a fixed 2.7 V output is required with a 200 mA current capacity. Consider the 280 mV typical dropout voltage for headroom calculations relative to the minimum input voltage. Evaluate the 70 dB PSRR requirement for noise-sensitive applications. Verify that the SSON004X1010-4 package footprint aligns with the PCB layout constraints and thermal dissipation requirements for the target environment.

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