Description
The LP3878-ADJ is an 800 mA adjustable output voltage regulator designed to provide high performance and low noise in applications
requiring output voltages as low as 1.0V.
Using an optimized VIP (Vertically Integrated PNP) process, the LP3878-ADJ delivers superior performance:
Ground Pin Current: Typically 5.5 mA @ 800 mA load, and
180 µA @
100 µA load.
Low Power Shutdown: The LP3878-ADJ draws less than 10 μA quiescent current when shutdown pin is pulled low.
Precision Output: Guaranteed output voltage accuracy is 1% at room temperature.
Low Noise: Broadband output noise is only 18 μV (typical) with 10 nF bypass capacitor.
The SP16130CH4RB Reference Board demonstrates a low IF receiver subsystem application including an ADC16V130 analog-to-digital converter (ADC) and LMK04031B clock conditioner which provides digitization and clocking as used in wireless infrastructure systems.
This subsystem reference design provides single to differential conversion and lowpass filtering of the input signal with an optimized, double-balun network and high dynamic range digitization to parallel LVDS outputs using the ADC16V130. The 125 MHz low-jitter, LVPECL clock signal for the ADC is generated by a LMK04031B clock conditioner which demonstrates less than 250 fs of total jitter over the input bandwidth of the ADC.
The SP16130CH4RB is factory configured for evaluation of input signals between 5 MHz and 52 MHz. Each board is populated with an analog input network which has a cascade of baluns for single-ended to differential conversion, and a filtering network optimized for these frequencies.
Evaluation of this reference board is simplified with the WaveVision 5.1 Data Capture Board and WaveVision 5 software.
Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
