The LP3990-Q1 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-Q1 will provide a 0.8-V 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.
The LP3990-Q1 is designed to be stable with space-saving ceramic capacitors with values as low as 1 µF.
Performance is specified for a –40°C to +125°C junction temperature range.
For output voltage options please refer to package option addendum (POA) or contact the Texas Instruments Sales Office.
For all available packages, see the orderable addendum at the end of the data sheet.WELL LINK CHIPS GROUP CO.,LIMITED FLAT/RM 1802 BEVERLY HOUSE 93-107 LOCKHART ROAD WANCHAI HK
