AP7375-33Y-13

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

The AP7375-33Y-13 is a fixed-output low-dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 3.3V output with a maximum load current of 300mA. The device supports a wide input voltage range from 3V to 45V and features a typical quiescent current of 2.1µA. Key electrical specifications include a dropout voltage of 35mV at 10mA and 350mV at 100mA, along with high power supply rejection ratio (PSRR) of 85dB at 1kHz. It incorporates integrated short-circuit and thermal shutdown protection functions.

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

• Provides a fixed 3.3V regulated output capable of delivering up to 300mA load current.
• Features an enable pin that accepts input voltages up to 45V for controlling the LDO output state.
• Ensures stability during line voltage transients and load current changes without overshoot voltage during startup or short-circuit recovery.

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

Verify the specific package code 'Y' corresponds to the SOT89 physical footprint required for your PCB layout. Confirm the suffix '-13' indicates tape and reel packaging compatible with standard automated assembly equipment. Ensure the selected component meets the environmental compliance standards specified in the manufacturer's datasheet before finalizing procurement orders.

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

Select this component when a wide input voltage range up to 45V is required alongside a fixed 3.3V output. It is suitable for designs needing low quiescent current consumption and high PSRR. Consider the SOT89 package for its thermal dissipation capabilities relative to smaller packages. Verify that the application does not require adjustable output voltages or automotive-grade qualification, which utilizes different part numbering.

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

This component belongs to the AP7375 series of wide input voltage ULDO regulators. The series offers multiple fixed output voltage options including 1.8V, 3.0V, 3.6V, and 5.0V. The 'Y' designation specifically identifies the SOT89 surface-mount package variant within this family, distinguishing it from SOT23, SOT25, and U-DFN2020-6 package options.
