Description

The LP3992 regulator is designed to meet the requirements of portable, battery-powered systems providing an accurate output voltage, low noise, and low quiescent current. Battery life will be prolonged by the ability of the LP3992 to provide a 1.5V output from the low input voltage of 1.9V. Additionally, when switched to a shutdown mode via a logic signal at the shutdown pin, the power consumption is reduced to virtually zero. The LP3992 also features short-circuit and thermal-shutdown protection.

The LP3992 is designed to be stable with space saving ceramic capacitors as small as 1.0µF.

The device is available in an SOT23-5 package. Performance is specified for a -40°C to 125°C temperature range.

For output voltages other than 1.5V and alternative package options, please contact your local NSC sales office.

Reliability Metrics

Part Number Process EFR Reject EFR Sample Size PPM LTA Rejects LTA Device Hours FITS MTTF (Hours)
LP3992IMF-1.5 CMOS7 0 16561 0 0 954000 4 270700104
LP3992IMFX-1.5 CMOS7 0 16561 0 0 954000 4 270700104

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.
