The SP6201ER-3.3/TR is a 300mA, low dropout (LDO) regulator manufactured by Sipex Corporation (now part of Exar Corporation). This LDO is designed to provide a stable 3.3V output voltage from a higher input voltage, with a low dropout voltage and low quiescent current, making it suitable for battery-powered and portable applications.

Applications:

• Portable Devices: Powers microcontrollers, memory, and other low-power components in smartphones, tablets, and other battery-operated devices.
• Wireless Communication Devices: Provides a regulated voltage supply for RF transceivers and other wireless communication ICs.
• Microcontroller Power: Used to regulate the supply voltage for microcontrollers in embedded systems.
• Sensor Power: Provides a stable voltage supply for sensors in industrial and consumer applications.
• Battery-Powered Equipment: Ideal for use in battery-powered equipment where efficiency and low quiescent current are important.

Features:

• Low Dropout Voltage: Operates with a minimal difference between the input and output voltage.
• 300mA Output Current: Capable of supplying up to 300mA of output current.
• Low Quiescent Current: Minimizes power consumption when the output is lightly loaded or unloaded.
• Stable with Ceramic Capacitors: Designed to work with ceramic output capacitors, reducing the size and cost of the application.
• Short-Circuit Protection: Protects the regulator and the load from damage in the event of a short circuit.

Benefits:

• Extended Battery Life: Low quiescent current and high efficiency maximize battery life in portable devices.
• Stable Output Voltage: Provides a consistent and reliable 3.3V output voltage, even with variations in input voltage and load current.
• Small Solution Size: The ability to use ceramic capacitors and the small package size minimize the overall solution size.
• Overload Protection: Protects the regulator and the load from damage due to overcurrent conditions.
• Simplified Design: Requires few external components, simplifying the design process.

Technical Specifications:

The SP6201ER-3.3/TR features a typical dropout voltage of less than 200mV at 300mA output current. The input voltage range is typically from 2.5V to 6V. The quiescent current is typically in the microampere range. The regulator is available in a small SOT-23 package.
