Linear Regulators


Ultra-low noise, ultra-high PSRR low dropout (LDO) linear regulators are key to power precision sensors, high speed data converters, frequency synthesizers and other noise-sensitive RF and microwave devices. Power by linear offers an outstanding family of robust positive and negative LDOs that produce ultra-low output noise and ultra-high power supply ripple rejection that cover a wide input voltage range, from 1.8 to 20 V, –20 to 1.8 V and a wide output current range, from 200 to 500 mA.

Non-standard configurations or selected electrical parameters are available on request.

RLC Electronics



SMD-packaged SAW-oscillators are extensively used in modern communication applications, since the technology features low phase noise, low microphonic (tolerance to vibration) and low jitter. SAW-oscillators exhibit limited tuning and limited operating temperature range (-20°C to 70°C), which limits the amount of correction needed to compensate frequency-drifts and tolerances of other components in the oscillator circuitry. The alternative is ovenized SAW-oscillators for extending the operating temperature but at the cost of high current and increase in size.
