TPS717185DSER

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TPS717185DSER is a fixed-output low-dropout linear regulator from the Texas Instruments TPS717 series. It provides a fixed output voltage of 1.85 V with a maximum output current of 150 mA. The device operates within an input voltage range of 2.5 V to 6.5 V and features a typical dropout voltage of 170 mV at full load. Quiescent current is specified at 45 uA, with line regulation at 125 uV/V and load regulation at 120 uV/mA. Voltage accuracy is maintained at 3%. It utilizes a WSON-6 (1.5x1.5 mm) surface-mount package and supports operation across a temperature range of -40°C to +125°C.
