Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for KA7812AE
Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview
The KA7812AE is a three-terminal positive linear voltage regulator from the KA78XXAE series, manufactured by onsemi. It provides a fixed output voltage of 12 V with a tolerance of ±2% at 25°C and supports an output current up to 1 A. The device operates within a junction temperature range of 0°C to +125°C and is housed in a TO-220 package. Key electrical characteristics include a maximum input voltage of 35 V for this output level, a dropout voltage of 2 V at 1 A, and ripple rejection of 60 dB at 120 Hz.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes
Verify the specific suffix 'AE' to confirm the ±2% output voltage tolerance and the 0°C to +125°C operating temperature range. Ensure the ordering part number matches the required package style, as the datasheet lists variations such as TU for rail packing. Cross-reference the manufacturer's updated nomenclature if sourcing from legacy Fairchild Semiconductor stock due to system integration changes.
Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes
Select the KA7812AE when a precise 12 V output with tighter tolerance than standard variants is required. This model is suitable for applications needing operation above 0°C junction temperature. Consider the 2 V dropout voltage requirement relative to the input supply. Verify that the thermal resistance values align with the available heat sinking capacity for the expected load current.
