AP78L05WG-7

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

The AP78L05WG-7 is a three-terminal positive linear voltage regulator from the AP78LXX series by Diodes Incorporated. It provides a fixed 5 V output with a maximum load current of 100 mA. The device operates within an input voltage range up to 36 V and functions reliably across a temperature range of -40°C to +125°C. Packaged in a compact SOT-23 surface-mount format, it integrates internal circuitry for current limiting and thermal shutdown to protect against overload conditions.

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

• Integrates internal current limit and thermal shutdown protection mechanisms to prevent device damage under fault conditions.
• Provides stable fixed positive voltage regulation suitable for local voltage distribution applications.
• Utilizes a small outline surface mount package design optimized for space-constrained electronic layouts.

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

• Local voltage regulation in distributed power systems
• Battery-powered equipment requiring efficient step-down conversion
• General-purpose voltage regulation in consumer electronics

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

Verify the specific suffix WG-7 to confirm the SOT-23 package and tape-and-reel orientation. Ensure compatibility with RoHS directives if environmental compliance is required for the target assembly. Cross-reference the manufacturer part number with official Diodes Incorporated documentation to validate pinout and electrical specifications before integration into the design.

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

Select this component when a fixed 5 V output is required with moderate current demands up to 100 mA. It is appropriate for designs prioritizing low component count and robust internal protection features over high-efficiency switching topologies. Consider the thermal performance in the SOT-23 package relative to the expected ambient temperature and power dissipation levels during operation.

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

This regulator belongs to the AP78LXX series, which offers various fixed output voltages including 5 V, 8 V, and 12 V. The series is designed as a drop-in replacement for traditional 78L05 regulators but utilizes modern surface-mount packaging technologies. It serves as a fundamental power management solution for simple linear regulation tasks in portable and industrial devices.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct functional equivalents include the standard 78L05 in TO-92 packages or other manufacturers' 78L05 variants. For surface-mount requirements, verify pinout compatibility with other SOT-23 regulated devices. Ensure that any substitute maintains the same 100 mA current rating and 5 V output tolerance.
