SNVS251J – MAY 2004 – REVISED SEPTEMBER 2014 LP3990 150-mA Linear Voltage Regulator for Digital Applications
1 Features 3 Description The LP3990 regulator is designed to meet the
requirements of portable, battery-powered systems
providing an accurate output voltage, low-noise, and
low-quiescent current. The LP3990 will provide a 0.8V output from the low input voltage of 2 V at up to a
150-mA load current. When switched into shutdown
mode via a logic signal at the enable pin (EN), the
power consumption is reduced to virtually zero. 1 1% Voltage Accuracy at Room Temperature
Stable with Ceramic Capacitor
Logic Controlled Enable
No Noise Bypass Capacitor Required
Thermal-Overload and Short-Circuit Protection
Input Voltage Range, 2 V to 6 V
Output Voltage Range, 0.8 V to 3.3 V
Output Current, 150 mA
Output Stable -Capacitors, 1 ВµF
Virtually Zero IQ (Disabled), < 10 nA …
