STLQ020C18R Description

Short technical summary and product information.

The STLQ020C18R is a positive fixed output low-dropout (LDO) voltage regulator from STMicroelectronics. It delivers a regulated 1.8V output with a maximum output current of 200mA. The device features a maximum dropout voltage of 0.16V at 200mA load, making it suitable for low headroom applications.

 

This regulator includes an enable control feature and offers protection against over-current and over-temperature conditions. It operates over a junction temperature range of -40°C to 125°C. The power supply rejection ratio (PSRR) is specified as 52dB to 45dB over a frequency range of 100Hz to 10kHz.

 

The STLQ020C18R is available in a surface-mount SOT-323-5 package, also known as 5-TSSOP, SC-70-5, or SOT-353. Its fixed output voltage and small footprint make it suitable for space-constrained power management applications.
