Product Description
STMicroelectronics STLQ020PU33R is a high-performance, five-channel low dropout voltage regulator designed for demanding electronic and embedded systems. Featuring a surface mount DFN6 package and supporting an output current up to 200 mA per channel, the regulator operates over a wide voltage range from 2 V to 5.5 V. Its extremely low-dropout voltage of 160 mV at maximum load and ultra-low quiescent current make it ideal for battery-powered and energy-sensitive applications.
With output voltage versions 0.8V and 4.5V, the STLQ020PU33R delivers precision power regulation for microprocessor cores, memory subsystems, analog circuits, and other critical loads. The device's adaptive biasing circuit ensures fast transient response and high power supply rejection ratio (PSRR), enhancing system stability even under varying load conditions.
Five output channels for advanced power partitioning in electronics design. 150 μA quiescent current with further reduction to 0.3 μA at no load for maximum energy savings. Logic-controlled shutdown reduces system power draw to just 5 nA when not actively in use.
Built-in overcurrent and thermal protection ensure robust operation in diverse environments. Wide temperature range from -40°C to +125°C enables application in industrial, laboratory, and automotive systems where reliability is critical.
Internal output discharge and short-circuit constant-current limiting extend component safety. Compliance with RoHS for environmentally sustainable manufacturing.
The STLQ020PU33R is especially suited to industrial control systems, portable instrumentation, laboratory equipment, telecommunications devices, and any application requiring precise, regulated multi-channel power distribution in a compact footprint.
