S-817B15AUA-CWET2U

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

The S-817B15AUA-CWET2U is a fixed-output linear low-dropout (LDO) voltage regulator manufactured by ABLIC Inc. It provides a stable 1.5 V output with a maximum continuous output current of 75 mA. The device features an ultra-low quiescent current of 1.2 µA, ensuring minimal power consumption in standby modes. It operates within an input voltage range up to 10 V and maintains a typical dropout voltage of 160 mV at full load. The unit offers high voltage regulation accuracy of ±2.0% and includes built-in protection against short circuits and thermal overload. It is housed in a compact SOT-89-3 surface-mount package and supports operation across a wide ambient temperature range from -40 °C to +85 °C.
