BU20TD2WNVX-TL

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

The BU20TD2WNVX-TL is a single-output fixed low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed 2 V output with a maximum load current of 200 mA. The device operates within an input voltage range of 1.7 V to 6 V and features a typical ripple rejection ratio of 70 dB. Key electrical parameters include a typical dropout voltage of 380 mV, a line regulation of 2 mV, and a load regulation of 10 mV. The quiescent circuit current is 35 uA, and the power dissipation capability is 560 mW. Voltage accuracy is specified at ±25 mV at 25°C. The component is housed in an SSON004X1010-4 package and supports 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 the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required output voltage tolerance and package type for the target application design. Cross-reference the datasheet revision date to validate parameter consistency before finalizing procurement orders.

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

Select this regulator when a compact footprint is critical due to its SSON004X1010-4 dimensions. Consider the 35 uA quiescent current for battery-operated systems requiring low standby consumption. Verify that the input voltage remains within the 1.7 V to 6 V range and that the load does not exceed the 200 mA limit under all operating conditions.

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

This component belongs to the BU**TD2WNVX series of CMOS LDO regulators. These devices are characterized by full-CMOS architecture, offering low power consumption and excellent noise characteristics. The series is designed for applications requiring stable voltage regulation in small form factors, distinct from higher-current or automotive-grade variants in the broader product portfolio.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

BU21TD2WNVX-TL: Same package and current rating but outputs 2.1 V. BU18TD2WNVX-TL: Same package and current rating but outputs 1.8 V. BU25TD2WNVX-TL: Same package and current rating but outputs 2.5 V. Verify output voltage compatibility before substitution.
