2 Applications
3 Description
The LP5951 regulator is designed to meet the requirements of portable battery-powered systems providing a regulated output voltage and low quiescent current. When switched to shutdown mode via a logic signal at the Enable (EN) pin, the power consumption is reduced to virtually zero.
The LP5951 is designed to be stable with small 1-μF ceramic capacitors. The device also features internal protection against short-circuit currents and over- temperature conditions.
Performance is specified for a –40°C to 125°C temperature range.
The device is available in fixed output voltages in the range of 1.3 V to 3.7 V. For availability, please contact your local TI sales office.
