BA33B00FP-E2

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

The BA33B00FP-E2 is a dual-output linear voltage regulator from ROHM Semiconductor, housed in a TO-252-3 package. It provides two fixed output voltages: one channel delivers 1 A at 3.3 V, while the second channel supplies 500 mA at 3.3 V. The device operates with an input voltage range of 4 V to 25 V and maintains a typical power supply rejection ratio (PSRR) of 55 dB. It features a maximum dropout voltage of 500 mV and supports surface-mount installation. The regulator functions within a temperature range of -40°C to +125°C, ensuring stable performance in various electronic applications.
