AP7375-30WR-7

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

The AP7375-30WR-7 is a wide input voltage range, low quiescent current linear regulator manufactured by Diodes Incorporated. It provides a fixed output voltage of 3.0V with a maximum load current capability of 300mA. The device operates within an input voltage range of 3V to 45V and features a typical dropout voltage of 350mV at 100mA. It includes an enable pin (EN) for power control and offers high power supply rejection ratio performance of 85dB at 1kHz. The component is housed in the SOT25 package with code WR.

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

• Features an integrated enable pin that accepts up to 45V input to control the LDO output state.
• Provides fast response times against line voltage and load current transients without overshoot during startup or short-circuit recovery.
• Includes internal thermal shutdown and current limit protection circuits to prevent damage from excessive power dissipation or short circuits.

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

• Battery-powered equipment
• Smoke detectors and sensors
• Microcontroller applications

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

Verify the specific ordering suffix 'WR' corresponds to the SOT25 package configuration when sourcing components. Confirm compliance with RoHS 3 and lead-free requirements as specified in the manufacturer documentation. Ensure the application environment remains within the recommended operating temperature range of -40°C to +85°C for optimal reliability.

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

Select this component for designs requiring a wide input voltage range up to 45V and low standby current consumption. The inclusion of an enable pin makes it suitable for systems requiring power management control. Verify that the required output voltage matches the fixed 3.0V specification and that the load current does not exceed the 300mA rating.

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. The series supports multiple fixed output voltages including 1.8V, 3.0V, 3.3V, 3.6V, and 5.0V. The WR suffix specifically denotes the SOT25 package variant equipped with an enable pin, distinguishing it from standard SOT25 versions without control inputs.
