AP1115AY50L-13

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

The AP1115AY50L-13 is a discontinued low dropout positive fixed-mode linear regulator manufactured by Diodes Incorporated. It provides a fixed 5V output with a maximum continuous current capability of 0.6A. The device operates with an input voltage range up to 18V and maintains regulation with a maximum dropout voltage of 1.3V at full load. It features built-in thermal shutdown and output current limiting for protection. The component is housed in a lead-free SOT-89-3 package.

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

This specific part number is officially obsolete and has been discontinued by the manufacturer. No new units are produced or available from authorized distribution channels. Procurement must rely exclusively on existing surplus inventory held by third-party distributors. Verify the authenticity and storage history of any available stock carefully before integration into designs.

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

Engineers should evaluate alternative components due to the discontinuation status of this regulator. When selecting replacements, ensure compatibility with the required 5V fixed output and 0.6A current capacity. Verify that substitute parts support the necessary 18V maximum input voltage and fit within the physical constraints of the SOT-89-3 footprint used in existing layouts.

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

The AP1115 series consists of low dropout positive regulators designed for applications requiring well-regulated supplies. This specific variant offers a fixed 5V output. The series is engineered to handle input voltages up to 18V while maintaining regulation with minimal voltage drop across the device under full load conditions.

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

The datasheet explicitly states there is no alternate part for this discontinued product. Engineers must identify equivalent LDO regulators from other manufacturers or newer generations within the same family that match the electrical specifications and pinout requirements.
