Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for KA7805AETSTU

KA7805AETSTU

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

The KA7805AETSTU is a three-terminal positive voltage regulator from the KA78XXAE series, manufactured by onsemi. It provides a fixed output voltage of 5 V with a tolerance of ±2% at 25°C. The device supports an output current up to 1 A and operates within a temperature range of 0°C to +125°C. It utilizes a TO-220 package with dual gauge leads and rail parking method. Key electrical characteristics include a maximum input voltage of 35 V for the 5 V variant, typical quiescent current of 6 mA, and dropout voltage of 2 V at 1 A load.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary
