AP7375-50Y-13

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

The AP7375-50Y-13 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated, providing a stable 5.0V output with a maximum load current of 300mA. It operates within a wide input voltage range from 3V to 45V and features an extremely low quiescent current of 2.1µA typical. The device incorporates an enable pin capable of handling up to 45V for power control. Packaged in SOT89-3 (Package Code Y), it includes integrated short-circuit and thermal shutdown protection. Key electrical characteristics include a typical dropout voltage of 350mV at 100mA and high power supply rejection ratio of 85dB at 1kHz.

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

Verify the specific package code 'Y' corresponds to the SOT89 form factor required for your PCB layout. Confirm that the 5.0V fixed output matches your system's voltage rail requirements. Ensure input voltages remain within the 3V to 45V operational limits to maintain regulation. Check datasheet specifications for thermal dissipation needs under your specific load conditions.

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

Select this component when a high-voltage input range up to 45V is required alongside a fixed 5V output. It is suitable for designs needing minimal standby current due to its 2.1µA quiescent profile. The SOT89 package offers a balance of thermal performance and footprint size. Consider the internal thermal shutdown if operating near maximum current limits or high ambient temperatures.

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

This part belongs to the AP7375 series of ultra-low dropout regulators designed for high-voltage applications. Unlike lower-voltage variants such as the AP7380, this series supports inputs up to 45V. The '50' suffix indicates the 5.0V fixed output version, while 'Y' denotes the SOT89 package. It serves as a robust power management solution for industrial and consumer electronics requiring reliable linear regulation.
