RT9078-10GJ5

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

The RT9078-10GJ5 is a low-dropout linear regulator manufactured by Richtek USA Inc., housed in a TSOT-23-5 surface-mount package. It provides a fixed output voltage of 1.0 V with a maximum continuous output current of 300 mA. The device operates within an input voltage range of 1.2 V to 5.5 V and features a typical quiescent current of 2 µA. Key electrical specifications include a typical power supply rejection ratio (PSRR) of 75 dB, a maximum dropout voltage of 200 mV at full load, and line/load regulation of 0.13% and 0.5%, respectively. It supports operation across an extended temperature range from -40°C to +125°C.
