AP1117ID50G-13

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

The AP1117ID50G-13 is a fixed-mode positive low dropout regulator manufactured by Diodes Incorporated. It provides a fixed 5.0V output with a maximum current capability of 1A. The device operates within an extended industrial junction temperature range of -40°C to +125°C and utilizes a TO252 (DPAK) surface-mount package. It requires an input voltage between 6.5V and 18V, ensuring stable regulation with a maximum dropout voltage of 1.4V at full load.

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

Verify that the specific suffix 'I' confirms the required -40°C to +125°C industrial operating temperature range. Confirm the 'D' package code matches the intended TO252 footprint on the PCB layout. Ensure the '-13' suffix corresponds to tape and reel packaging requirements for automated assembly processes.

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

Select this component when a fixed 5.0V rail is needed with high current drive in harsh environments. Verify that the input voltage remains above the minimum dropout threshold during all load transients. Check that the PCB copper area supports the necessary thermal dissipation for the expected power loss.
