STLQ020C18R

STLQ020C18R Description

The STLQ020C18R from STMicroelectronics is a high-performance, low-dropout (LDO) linear voltage regulator designed for precision power management in compact electronic systems. This fixed-output regulator delivers a stable 1.8V with a maximum output current of 200mA, making it ideal for low-power applications. With an ultra-low quiescent current of 1 µA and a dropout voltage as low as 0.16V @ 200mA, it ensures efficient operation even in battery-powered devices. The device operates over a wide input voltage range up to 5.5V and features robust protection mechanisms, including over-current and over-temperature safeguards. Packaged in a SOT323-5 form factor, it is optimized for space-constrained designs.
