AP7343-15W5-7

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

The AP7343-15W5-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated, providing a stable 1.5V output with a maximum current of 300mA. It operates within an input voltage range of 1.7V to 5.25V and features high power supply rejection ratio (PSRR) of 75dB at 1kHz. The device utilizes a CMOS process for low quiescent current consumption of 35µA and includes an enable pin for power management. Packaged in SOT-25, it offers ±1% output voltage accuracy and supports an operating temperature range from -40°C to +85°C.

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

Verify the specific suffix W5 corresponds to the SOT-25 package configuration required for your design. Confirm that the non-discharge variant meets system requirements, as discharge versions carry a 'D' suffix. Ensure compatibility with RoHS and halogen-free standards if environmental compliance is mandatory for the target market.

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

Select this component when a fixed 1.5V rail is needed with minimal footprint. The SOT-25 package suits space-constrained layouts. Consider the AP7343D variant if output discharge upon shutdown is necessary. Verify input voltage stability remains above the minimum threshold during load transients to maintain regulation.

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

This part belongs to the AP7343 series of 300mA high PSRR low-noise LDOs. It shares architectural similarities with other Diodes Incorporated regulators but is distinct in its fixed 1.5V output and specific packaging. The series targets portable electronics requiring efficient power management in compact form factors.
