KA723D

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

The KA723D is a monolithic precision voltage regulator manufactured by onsemi in a 14-SOP package. It supports positive or negative supply operation with an input voltage range up to 40V and an adjustable output voltage from 2V to 37V. The device delivers an output current of 150mA without requiring an external pass transistor. Key electrical characteristics include a typical line regulation of 0.01%, load regulation of 0.03%, and ripple rejection of 86dB at 100kHz. The reference voltage is typically 6.80V, and the standby current drain is 2.0mA. It operates within a temperature range of 0°C to +70°C.
