STMicroelectronics LDR1833K7-R is a dual-output positive fixed linear voltage regulator. This component provides independent 1.8V and 3.3V outputs, capable of delivering up to 1A and 500mA respectively. Designed for surface mount applications within a 7-SPAK package, it features an enable pin for control. The LDR1833K7-R boasts a low quiescent current of 50 µA and a supply current of 1.6 mA maximum. Protection features include over current, over temperature, and short circuit. With a maximum input voltage of 15V and a power supply rejection ratio (PSRR) of 70dB at 120Hz, this regulator is suitable for applications in automotive, industrial, and consumer electronics. The device operates across a temperature range of -40°C to 125°C and is supplied in a Tape & Reel (TR) package.
