Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for KA78L05AZBU

KA78L05AZBU

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

The KA78L05AZBU is a fixed voltage monolithic integrated circuit linear regulator manufactured by onsemi, formerly Fairchild Semiconductor. It provides a nominal output voltage of 5V with a ±5% tolerance and supports a maximum continuous output current of 100mA. The device operates within an input voltage range up to 30V for the 5V variant and features a TO-92 three-terminal package. Key electrical characteristics include a typical quiescent current of 2.0mA, line regulation of 8mV (typical), and load regulation of 11mV (typical). It incorporates internal thermal overload protection and short-circuit current limiting.
