AP7342D-3028FS6-7

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

The AP7342D-3028FS6-7 is a dual low-dropout regulator from Diodes Incorporated, packaged in an X2-DFN1212-6 footprint. It provides fixed output voltages of 3.0V on Channel 1 and 2.8V on Channel 2. The device guarantees an output current of 150mA per channel with a wide input voltage range of 1.7V to 5.25V. Key electrical characteristics include a ripple rejection ratio of 75dB at 1kHz, low output noise of 60µVrms (10Hz to 100kHz), and a quiescent current as low as 35µA. Dropout voltage is specified at 0.29V maximum for the 3.0V output and 0.34V maximum for the 2.8V output at full load.

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

What is the function of the 'D' suffix in the part number?

The 'D' suffix indicates that the regulator includes an internal auto-discharge resistor connected to the output pins to rapidly bleed off stored charge when the device is disabled.

How does the enable pin control the regulator operation?

Driving the EN pin high enables the respective channel output, while pulling it low activates shutdown mode. The pin must not be left floating during operation.
