BD900M5WHFP-CTR

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

The BD900M5WHFP-CTR is an automotive-grade low-dropout (LDO) linear regulator from ROHM Semiconductor's QuiCur series. It features a maximum output current of 500 mA and supports input voltages up to 42 V, with a minimum operating voltage of 3 V. The device provides adjustable output voltage regulation within a range of 1 V to 18 V. Key electrical specifications include a typical ripple rejection ratio of 70 dB at 120 Hz and a maximum dropout voltage of 1.3 V at full load. It operates reliably across an extended junction temperature range from -40 °C to +150 °C.
