KA7805ERTM

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

The KA7805ERTM is a three-terminal positive linear voltage regulator from the KA78XXE series, manufactured by onsemi. It provides a fixed output voltage of 5 V with a tolerance of ±4% at 25°C. The device supports an output current up to 1 A and operates within an input voltage range of 7 V to 20 V. Electrical characteristics include line regulation of 100 mV (VI = 7 V to 25 V) and load regulation of 100 mV (IO = 5 mA to 1.5 A). The quiescent current is typically 8 mA. The component is housed in a D-PAK surface-mount package and is rated for an operating temperature range of -40°C to +125°C.
