BA033CC0T

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

The BA033CC0T is a fixed-output low-dropout (LDO) regulator manufactured by ROHM Semiconductor. It provides a stable 3.3 V output with a maximum current capacity of 1 A. The device operates within an input voltage range of 4 V to 25 V and withstands up to 35 V. Key electrical parameters include a typical dropout voltage of 0.3 V at 0.5 A, ripple rejection of 55 dB, and load regulation of 50 mV from 5 mA to 1 A. It features ±2.0% output accuracy at 25°C and consumes 2.5 mA of circuit current. The component supports through-hole mounting in a TO-220FP-3 package and functions reliably across a temperature range of -40°C to 125°C.
