SSP78XX is three-terminal positive regulators. One of these regulators can deliver up to 1.5A of output current. The internal limiting and thermal-shutdown features of the regulator make them essentially immune to overload. When used as a replacement for a zener diode-resistor Combination, an effective improvement in output impedance can be obtained, together with lower quiescent current.
SSP6206
SSP6206 series are a highly precise, lower consumption, 3 terminal, positive voltage regulators manufactured using CMOS and laser trimming technologies. The series provides large currents with a significantly small dropout voltage .
The SSP6206 consists of a current limiter circuit, a driver transistor, a precision reference voltage and an error correction circuit. The series is compatible with low ESR ceramic capacitors. The current limiter’s foldback circuit operates as a short circuit protection as well as the output current limiter for the output pin. Output voltages are internally by laser trimming technologies. The output voltage can be selected from 1.5V to 3.6V. SSP6206 series are available in SOT-23,SOT23-3 and SOT89 packages.
SSP1852
The SSP1852 is a high accuracy polyphase electrical energy measurement IC. The part specifications surpass the accuracy requirements as quoted in the IEC62053-2x standard. The only analog circuitry used in the SSP1852 is in the analog-to-digital converters (ADCs) and reference circuit. All other signal processing (such as multi-plication, filtering, and summation) is carried out in the digital domain. This approach provides superior stability and accuracy over extremes in environmental conditions and over time.
The SSP1852 supplies average real power information on the low frequency outputs, F1 and F2. These logic outputs may be used to directly drive an electromechanical counter or to interface with an MCU. The CF logic output gives instanta-neous real power information. This output is intended to be used for calibration purposes.
The SSP1852 includes a power supply monitoring circuit on the VDD pin. The SSP1852 remains inactive until the supply voltage on VDD reaches 4 V. If the supply falls below 4 V, no pulses are issued on F1, F2, and CF. Internal phase matching circuitry ensures that the voltage and current channels are phase matched. An internal no load threshold ensures the part does not exhibit any creep when there is no load.
The SSP1852 is available in a 24-lead SOIC package.
SSP1220
The SSP1220 is a precision, 24-bit, analog-to-digital converter (ADC) that offers many integrated features to reduce system cost and component count in applications measuring small sensor signals.
