SD2900 Frequently Asked Questions (FAQ)
-
STMicroelectronics provides a recommended PCB layout in the application note AN5323, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
-
The SD2900 output voltage range can be configured by selecting the appropriate external resistors (RFBT and RFB) and capacitors (COUT) according to the datasheet and application notes. The output voltage range can be adjusted from 0.8V to 3.3V in 50mV steps.
-
The SD2900 can handle input voltages up to 5.5V, but it's recommended to keep the input voltage below 5V to ensure reliable operation and minimize power dissipation.
-
To ensure stability, follow the recommended PCB layout, use a sufficient output capacitor (COUT) with a low equivalent series resistance (ESR), and add a small ceramic capacitor (typically 10nF to 100nF) between the VIN and GND pins to filter out high-frequency noise.
-
The typical startup time for the SD2900 is around 1ms to 2ms, depending on the input voltage, output voltage, and external component values. This can be critical in applications where fast startup is required.
