Battery life is prolonged by the ability of the LP3992 to provide a 1.5-V output from the low input voltage of 1.9 V. Additionally, when switched to a shutdown mode via a logic signal at the enable (EN) pin, the power consumption is reduced to virtually zero. The LP3992 also features shortcircuit and thermal-shutdown protection. The LP3992 is designed to be stable with spacesaving ceramic capacitors as small as 1 µF. Performance is specified for a –40°C to +125°C temperature range. For output voltages other than 1.5 V, and for additional package options, contact TI. 2 Applications GSM Port...
