Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for KA79L08AZTA

KA79L08AZTA

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

The KA79L08AZTA is a fixed negative linear voltage regulator from the KA79LXXA series, manufactured by onsemi. It provides a nominal output voltage of -8 V with a maximum output current of 100 mA in a TO-92-3 package. The device operates within an input voltage range of -10.3 V to -23 V and supports junction temperatures from 0°C to +125°C. Key electrical specifications include a line regulation of 175 mV (max), load regulation of 80 mV (max), ripple rejection of 55 dB at 120 Hz, and a typical quiescent current of 6.0 mA.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status via the specific datasheet revision. Check for End-of-Life (EOL) notices or Product Change Notifications (PCN) as availability may be restricted. Ensure the TO-92-3 package matches the design footprint requirements before procurement.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a stable negative rail is required for low-current analog or digital loads. Verify that the input voltage remains sufficiently above the -8 V output to maintain regulation. Consider the thermal dissipation capabilities of the TO-92 package under expected load conditions. Ensure the application does not exceed the 100 mA continuous output current limit.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the KA79LXXA family of 3-terminal negative voltage regulators. The 'KA' prefix indicates Fairchild Semiconductor origin, now managed by onsemi. The 'L' suffix denotes the 100 mA current class, distinguishing it from higher-power variants. The '08' specifies the -8 V fixed output voltage option within the series.
