TCR8BM09A,L3F

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

The TCR8BM09A,L3F is a fixed-output linear voltage regulator from Toshiba, providing a stable 0.9V output with an 800mA maximum current capability. It operates within an input voltage range up to 5.5V and features a typical dropout voltage of 17mV at full load. The device incorporates low quiescent current of 20µA and high power supply rejection ratio (PSRR) of 98dB at 1kHz. It includes protection mechanisms such as overcurrent, thermal shutdown, and under-voltage lockout, functioning reliably across a temperature range of -40°C to +85°C in a compact 5-DFNB package.
