RT9078-12GJ5 Description

Short technical summary and product information.

The RT9078-12GJ5 is a fixed output linear voltage regulator (LDO) designed by RICHTEK. It delivers a regulated 1.2V output with a maximum output current of 300mA. The device operates over an input voltage range from 1.2V to 5.5V, making it suitable for low-voltage battery-powered applications.

 

Key electrical characteristics include a typical quiescent current of only 2µA, which helps extend battery life in portable devices. The dropout voltage is typically 150mV at full load (300mA), allowing efficient regulation even with small input-to-output voltage differentials. The regulator offers high power supply rejection ratio (PSRR) of 75dB at 1kHz, ensuring clean output in noise-sensitive circuits.

 

The device includes over-current and over-temperature protection for reliable operation. An enable control pin allows the regulator to be turned on or off for power sequencing. The RT9078-12GJ5 is housed in a compact TSOT-23-5 surface-mount package, ideal for space-constrained designs. It operates over a temperature range of -40°C to +85°C.
