BU33TD2WNVX-TL

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

The BU33TD2WNVX-TL is a single-output positive fixed CMOS LDO regulator by ROHM Semiconductor. It provides a 3.3 V output with a maximum current of 200 mA. The device operates within an input voltage range of 1.7 V to 6.5 V and features a typical dropout voltage of 220 mV at full load, with a maximum of 420 mV. Quiescent current is 35 µA. It offers 70 dB typical ripple rejection and ±1% output accuracy. Protection includes thermal shutdown, over-current protection, and discharge functions. Operating temperature spans -40°C to +85°C in an SSON004X1010-4 package.
