AP7340D-33FS4-7 3.3V 150mA LDO, High PSRR voltage regulator
The AP7340D-33FS4-7 is a high-performance Low Dropout (LDO) linear voltage regulator designed by Diodes Incorporated. It is specifically engineered for low-power applications requiring high efficiency, low noise, and high Power Supply Rejection Ratio (PSRR). This regulator features a fixed output voltage of 3.3V, a maximum output current of 150mA, and an input voltage range of 1.7V to 5.25V.
Features
This LDO regulator offers several key features that make it suitable for a wide range of applications. It has a high PSRR of 75dB at 1kHz, ensuring excellent noise rejection and stable output voltage. The regulator also features low output noise of 60μVrms over a frequency range of 10Hz to 100kHz. Additionally, it has a low dropout voltage of around 0.21V at 150mA, allowing it to operate efficiently even with low input-to-output voltage differences. The device includes an enable input (EN) for power control and is available in a compact X2-DFN1010-4 package, which is ideal for space-constrained designs.
The AP7340D-33FS4-7 operates within a wide temperature range of -40°C to +85°C, making it suitable for both commercial and industrial applications. It has a maximum input voltage of 6.0V and a maximum power dissipation of 400mW. The regulator ensures high output voltage precision with a tolerance of ±1% and a low quiescent current of 35μA, which is crucial for battery-powered devices.
Applications
The AP7340D-33FS4-7 is widely used in applications that require efficient power management and low noise. These include smartphones, tablets, RF power supplies, cameras, portable media players, wireless adapters, and other low-power handheld devices. Its high PSRR and low noise characteristics make it ideal for sensitive analog circuits and low-power systems.
