BU29JA2MNVX-CTL

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

The BU29JA2MNVX-CTL is a Full CMOS Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed 2.9V output with a maximum load current of 200mA. The device operates within an input voltage range of 1.7V to 6V and withstands up to 6.5V. Key electrical parameters include a typical dropout voltage of 0.26V at 0.2A, a circuit current of 35µA, and ripple rejection of 70dB. It features ±2.0% output accuracy and requires a 0.22µF output capacitor. The component is housed in a compact SSON004R1010 package (1.00mm × 1.00mm × 0.60mm) and supports functional safety analysis.

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

Verify the specific suffix 'CTL' corresponds to the required tape and reel packaging configuration with a standard quantity of 5,000 units per reel. Confirm RoHS compliance status and Functional Safety (FS Supportive) classification requirements against your project's quality standards. Ensure the ordering part number matches the exact 2.9V output variant to avoid compatibility issues with downstream circuitry.

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

Select this component when a fixed 2.9V rail is required with minimal footprint and low static current. The 200mA output capacity suits moderate load applications. Verify that the input voltage remains above 1.7V and below 6V during operation. The requirement for a 0.22µF output capacitor must be accommodated in the design. Consider the -40°C to 125°C operating temperature range for environmental suitability.
