XC6206P332MR (662K) 3.3V 200mA LDO Positive Voltage Regulator SOT-23

XC6206P332MR (662K) 3.3V 200mA LDO Positive Voltage Regulator SOT-23 provides a precise and highly stable power source for low-power electronic devices and battery-operated systems. This high-accuracy, low dropout (LDO) CMOS voltage regulator delivers a fixed 3.3V output while maintaining an extremely low quiescent current. Consequently, it extends battery life in portable applications where every microampere of power conservation matters. The device utilizes a built-in current limiter and a feedback circuit to ensure reliable performance under varying load conditions. Furthermore, its miniature SOT-23 package makes it an ideal solution for space-constrained PCB designs. Therefore, you should integrate the XC6206P332MR into your next project to achieve efficient voltage regulation with minimal board footprint.

Key Features:

• Ultra-Low Quiescent Current: The device consumes typically only 1.0 μA, which significantly reduces standby power consumption in battery-powered gadgets.
• Low Dropout Voltage: It features a low dropout of approximately 250 mV at a 100 mA load, allowing the regulator to maintain a stable output even as the input battery voltage nears 3.3V.
• High Output Accuracy: CMOS technology ensures a highly precise output voltage with a tolerance of ±2% under standard operating conditions.
• Integrated Protection: The internal current limiting circuit protects the regulator and the connected load from accidental over-current or short-circuit damage.
• Ceramic Capacitor Compatible: This regulator remains stable even when using low-ESR ceramic capacitors, simplifying the selection of external filtering components.
