Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DER' corresponds to the required tape-and-reel packaging quantity and orientation as defined in the official datasheet. Confirm that the fixed 3.0V output aligns with the target circuit design requirements before procurement. Ensure compatibility with the specified operating temperature range and thermal dissipation capabilities of the UFDFN package during integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 3.0V output is required without external resistor networks. Choose the XC9236 series over XC9235 or XC9237 variants if automatic load-dependent switching between PWM and PFM modes is preferred for optimal efficiency. Consider the 1.8V minimum input voltage capability for applications powered by partially discharged single-cell batteries.

Voltage Regulators - DC DC Switching Regulators Part Context

The XC9236B3BDER-G belongs to the XC9235/XC9236/XC9237 family of 600mA synchronous step-down converters. This series distinguishes itself through built-in driver transistors that permit the use of low-ESR ceramic capacitors, reducing overall solution size. The B-type designation indicates a fixed output voltage variant, differing from adjustable types that require external resistors.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations
