BU34TD2WNVX-TL

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

The BU34TD2WNVX-TL is a fixed-output positive linear voltage regulator manufactured by ROHM Semiconductor. It provides a stable 3.4 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 power supply rejection ratio (PSRR) of 70 dB. It exhibits a dropout voltage of 220 mV at full load, with a maximum of 420 mV. Line regulation is specified at 2 mV, and load regulation at 10 mV. Quiescent current is 35 uA, with a power dissipation rating of 560 mW. Voltage accuracy is 1%. It functions in temperatures from -40°C to +85°C and is housed in an SSON-4 package.
