The Texas Instruments UCC284DP-ADJ is a negative linear-series pass regulator designed for low-dropout applications requiring low quiescent power. Fabricated with BCDMOS technology, it is well-suited for low input-to-output differential applications.
This regulator can pass 0.5 A while requiring only 0.2 V of input-voltage headroom. The dropout voltage decreases linearly with output current, being less than 20 mV at 50 mA. Quiescent current consumption under normal conditions is typically 200 uA. An integrated charge pump is internally enabled when operating near dropout with low VIN.
Key electrical specifications include a maximum input voltage of -3.2 V and a minimum input voltage of -15 V. The maximum output current is 0.5 A. The output voltage is adjustable, with a maximum of -1.2 V and a minimum of -15 V. Noise is typically 200 µVrms, and accuracy is 2.5%. Protection features include over temperature, short circuit, and under voltage lockout (UVLO).
The UCC284DP-ADJ is available in an 8-SOIC package and is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C.
