Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for KA7812E

KA7812E

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

The KA7812E is a three-terminal positive linear voltage regulator from the KA78XXE series, manufactured by ON Semiconductor. It provides a fixed nominal output voltage of 12 V with a tolerance of ±4% at 25°C. The device supports an output current up to 1 A and operates within a junction temperature range of -40°C to +125°C. It utilizes a TO-220 package and incorporates internal protections including thermal overload shutdown, short-circuit limiting, and safe operating area protection.

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

Integrated thermal overload protection for automatic shutdown under excessive heat conditions
Internal short-circuit current limiting to safeguard against output faults
Output transistor safe operating area protection ensures stability across varying load conditions

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

DC parameter regulation circuits
Ripple rejection applications
Negative output voltage circuit configurations
Split power supply designs

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

Verify the specific ordering suffix (e.g., TU) against the manufacturer's official documentation to confirm the exact package variant and parking method. Ensure compatibility with the required operating temperature range (-40°C to +125°C). Confirm that the input voltage remains within the absolute maximum ratings specified in the datasheet to prevent device damage.

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

Select this component when a fixed 12 V output is required with up to 1 A load capability. Consider the TO-220 package for through-hole mounting requirements. Evaluate thermal management needs, as adequate heat sinking is necessary to sustain output currents exceeding typical levels without triggering thermal protection.

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

This device belongs to the KA78XXE series of three-terminal positive regulators. The series offers multiple fixed output voltages including 5, 6, 8, 9, 10, 12, 15, 18, and 24 V.
