PQ025EH01ZZ is listed in the Voltage Regulators - Linear, Low Drop Out (LDO) Regulators range at ChipApex. The manufacturer field lists Sharp Microelectronics. Its product description is IC REG LINEAR 2.5V 1A TO263. Review the specifications below when checking this part for your BOM.
The PQ025EH01ZZ is a low voltage operation, low power-loss voltage regulator from the PQxxxEZ02Z series manufactured by Sharp Microelectronics. It features a minimum operating voltage of 2.35V, allowing functionality with a 2.5V input to provide an output voltage range of 1.5V to 1.8V. The device exhibits low dissipation current at no load, with a maximum rating of 2mA. Designed for compact electronic applications, it supports power supplies for personal computers and peripheral equipment such as DVD players or set-top boxes.
Verify the specific output voltage configuration required for the application, as the series supports a range of 1.5V to 1.8V outputs. Confirm that the system operates within the minimum 2.35V input requirement. Ensure compatibility with the low dissipation current specifications for battery-powered or energy-efficient designs. Cross-reference the package dimensions provided in the official datasheet to ensure mechanical fit within the target enclosure.
Select this component when designing systems requiring stable regulation from very low input voltages near 2.5V. It is appropriate for applications where minimizing quiescent current is critical for extending battery life or reducing heat generation. Consider the specific output voltage variant needed within the 1.5V to 1.8V range. Evaluate if the IP67 environmental resistance of associated sensors or other system components aligns with the regulator's operational environment.
This part belongs to the PQxxxEZ02Z series of low power-loss voltage regulators. These devices are engineered for low voltage operation, distinguishing them from standard regulators that require higher input thresholds. The series is targeted at portable electronics and peripherals where power efficiency and low standby current are primary design constraints.
