AP7342D-1815FS6-7

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

The AP7342D-1815FS6-7 is a dual low-dropout regulator from Diodes Incorporated, packaged in an X2-DFN1212-6 format. It provides fixed output voltages of 1.8V on Channel 1 and 1.5V on Channel 2. The device guarantees a continuous output current of 150mA per channel with ±1% accuracy at +25°C. Operating within a 1.7V to 5.25V input range, it features a typical ripple rejection of 75dB at 1kHz and a low output noise of 60µVrms across the 10Hz to 100kHz bandwidth.

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

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance and lead-free status against current regulatory standards. Validate package marking codes (CAE) and thermal pad grounding requirements during assembly. Ensure EN pins are driven high or low rather than left floating to maintain stable operation.

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

Select this part for designs requiring two distinct regulated rails from a single compact footprint. Verify that the required load currents remain within the 150mA limit per channel. Consider the specific dropout voltage characteristics relative to the minimum input voltage available in the system. Evaluate PCB layout constraints to accommodate the small X2-DFN1212-6 package dimensions.

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

This component belongs to the AP7342 series of dual LDO regulators designed for low-power handheld communication equipment. It utilizes a CMOS process to achieve low quiescent current and high PSRR. The datasheet explicitly states that the AP7342 is not recommended for new designs and suggests using the AP7345D instead.
