SP6661 is a high frequency 200mA charge pump inverter or doubler from Sipex Corporation, which features 92% power efficiency, selectable 120kHz/900kHz oscillator frequency, low output resistance, low voltage battery operation, high output current, low profile solution and 1.5V inverter startup guaranteed. It is ideal for 3.6V lithium ion battery or 5.0V input and is pin-compatible with the high-current upgrade of the ICL7660 and 660 industry standard, with the smallest package available for the 660 industry standard – 8 pin µSOIC.

The SP6651A is a high efficiency 800mA synchronous buck regulator from Sipex Corporation, ideal for portable applications that use a Li-Ion or 3 cell alkaline/NiCD/NiMH input. The SP6651A features a proprietary control loop, 20µA light load quiescent current, and 0.3Ω power switches, providing excellent efficiency across a wide range of output currents. As the input battery supply decreases towards the output voltage the SP6651A seamlessly transitions into 100% duty ratio operation, further extending useful battery life. The SP6651A is protected against overload and short circuit conditions with a precise inductor peak current limit. Other features include programmable under voltage lockout and low battery detection, externally programmed output voltage down to 1.0V, logic level shutdown control, and 140°C over temperature shutdown.

The SPX29300/01/02/03 are 3A, highly accurate voltage regulators with a low dropout voltage of 450mV dropout (typical) @ 3A. These regulators are specifically designed for low voltage applications that require a low dropout voltage and a fast transient response. They are fully fault protected against over-current, reverse battery, and positive and negative voltage transients.

SPX2431L Precision Adjustable Shunt Regulator is a 3-terminal adjustable shunt voltage regulator providing a highly accurate bandgap reference (0.5%) and extremely low operating current (100µA).
