Frequently Asked Questions

How do I choose between XZ1001 and XZ1002?

Choose XZ1001 for noise-sensitive applications requiring ultra-low noise (8μVrms) and high PSRR (75dB). Select XZ1002 for battery-powered applications where quiescent current (1μA) is more important than noise performance. XZ1001 is ideal for RF and analog circuits, while XZ1002 is perfect for always-on digital rails.

XZ1001 for noise-sensitive RF/analog; XZ1002 for low-power battery applications.

What is PSRR and why does it matter?

PSRR (Power Supply Rejection Ratio) indicates how well an LDO rejects noise from its input supply. Higher PSRR means better filtering of input ripple. XZ1001 offers 75dB PSRR, meaning it rejects 99.98% of input ripple at 1kHz. This is critical when using an LDO after a switching converter.

High PSRR is important for post-regulation; choose XZ1001 for best PSRR performance.

What is dropout voltage?

Dropout voltage is the minimum input-to-output voltage differential required for the LDO to maintain regulation. XZ1001 has 150mV dropout at 300mA, meaning the input must be at least 150mV higher than the output. Lower dropout allows operation with lower input voltages.

Consider dropout voltage when battery is near end of discharge; ensure sufficient headroom for worst-case conditions.

Can I use ceramic capacitors with Silicontent LDOs?

Yes, Silicontent LDOs are designed to be stable with ceramic capacitors. Use X5R or X7R dielectric capacitors with values of 1μF to 10μF. Place capacitors close to the LDO pins for best performance. Ceramic capacitors provide low ESR and small size.

Use ceramic capacitors for best performance; place close to LDO pins for stability and noise reduction.

Are Silicontent LDOs suitable for automotive applications?

Yes, Silicontent offers automotive-grade LDOs that are AEC-Q100 qualified. These devices meet automotive reliability requirements and are suitable for infotainment, ADAS, and body electronics applications. Contact BeiLuo Electronics for automotive product availability.
